The Subwoofers Deflector product range & related transducers It is imperative that electro-acoustic speakers are used in full compliance with safety regulations. Professional electro-acoustic systems are capable of producing high levels of sound pressure, and must therefore be used with care. Loss of hearing is cumulative, and may result after exposure for long periods at sound pressure levels above 90 dB. Never stand close to the electro-acoustic speakers working at high volume. For ground positioning, always check that the base is flat and stable. Do not pile speakers up too high in outdoor areas, where the wind may cause the stack to become unstable. Suspended systems must be assembled by qualified and experienced staff and professional riggers. 7. System Guida generale installation all’uso dei Subwoofers 2. GENERAL INFORMATION 1.

Among many reasons why, Deflector Line features can be distinguished from those of competring products within the same sector by the following characteristics: • a cabinet made out of multuply Canadian birchwood with a thickness of 15 mm, • reinforced internal angles for the suspension system in 420ML alloy iron, • pratical aluminium flying tracks on the upper and lower walls of the speakers, • ergonomic handles with a double grip, • sound-transparent grid - it does not obstruct the holes in the internal sponge - , secured to the chassis with retractable screws, that are embedded in specific holes in the wood, • a neodymium woofer with a 4” coil supported by fibreglass, • an innovative AWSH™ (Acoustic Wave Shaped Horn), • proprietary technology curved deflector. 3. CONTROLLED AIR FLOW TECHNOLOGY All of the Deflector line upper modules (with the exception of the “small” 2-way model XTD88) have been designed and produced with an extremely innovative bass reflex. The classic tubular shape has been superseded by a “sail-side” duct placed in the immediate vicinity of the woofer, between it and the base of the cabinet, following its circular profile. This solution was reached during the design stage, relying on particular fluido-dynamic simulations, with the aim of minimizing air turbulence inside the cabinet and the duct itself. As well as being considered for different types of clusters based on the horn’s dispersion angles, the mixed inclination of the outer walls has also been optimized, taking into account the afore-mentioned simulations, with a view to harmonizing the sound pressure inside the cabinet and reducing resonance to the minimum. While standing in front of a speaker and sectioning it lengthwise with a perpendicular plane, it is easy to identify the profile of the deflector, which has a convex-concave shape (according to the convection that mentions the intrados first, which is the lower surface, and then the extrados, the upper surface) and also a camber – this is defined as the distance between the wing chord and the mean line: concerning the classic “roundedness” of the wing surface – this is extremely reduced so as not to unnecessarily obstruct the air flow controlled by the deflector. As above-mentioned, the X-Treme design team carried out special fluid dynamic simulations and created numerous prototypes in laboratory; all of this had the aim of reaching the long-awaited air flow control generated inside the cabinet and the duct. From irregular and vortical, due to the “whirlpool” of the bass reflex, this flow is transformed – in a non-viscous environment and at sufficient distance from the walls – into a regular and laminar one, thanks also to the intervention of a specific back frame, which has a 5 cm thickness and to the 5 degrees tilt of the plane where the loudspeaker is mounted. As well as being conceived for its different types of clusters in accordance with the horn’s dispersion angles, this mixed tilting of the outer walls was designed to eliminate typical turbulences, which particularly appear on the tuning tube: this means that the waves reflecting on the woofer are minimized and, owing to the precise cone-duct alignment (the tolerance field is measured in mm), the resonance and phase cancellation in the input and output points disappear completely, with resulting harmony and sound pressure optimization inside the cabinet. Fig. 2 Base definitions of Controlled Air Flow Technology 4. ACOUSTIC WAVE SHAPED HORNTM The aluminium AWSHTM (Acoustic Wave Shaped Horn) was designed and manufactured using CAE tools (Computer Aided Engineering) to guarantee the sound centre and woofer alignment, while keeping the planes containing the openings of the woofer cone and the horn itself perfectly fitted together. The production process is carried out via die casting, by pouring the melted alloy into a permanent metallic mould or die, specifically designed for this original product on the specifications of the X-Treme engineers. The pressured manufacturing process allows the mould cavity to be filled very quickly and the probable injection due to the reduction caused by solidification to be compensated. This produces the following effects: perfect and total cavity filling and a fine crystalline structure of the part, free of imperfections. In the XTD88 and XTD1015 models, thanks to a special AWSHTM horn being fitted in the opposite concave of the speaker, it is possible to rotate the whole medium-high section (horn+driver+panel) by 90°, therefore making it possible to maintain the same coverage at high frequencies, both when the speaker is in position, standard, vertical and when it is mounted horizontally. By simply unscrewing the 8 screws in the external squared flange, it can be rotated without damaging the connection cables or compromising the other internal elements. Fig. 1 Bass reflex with curved deflector 3/12 User’s manual Fig. 5 XTD12 and XTD12/A models The XTD15 model, like the amplified version XTD15/A, has a 600 W (AES) 15” woofer, a higher efficiency than the 12” XTD12, with a Neodymium magnet and a 110 W driver with a Polyimide-titanium membrane, a 3” coil, 1.4” throat diameter, and an in-built 1.4” AWSHTM aluminium horn. The horn dispersion angle is on average 90° horizontal by 50° vertical. The speaker can produce a maximum SPL peak of 134 dB. Fig. 3 Horizontal and vertical installation, maintaining horn orientation 5. SUBWOOFERS The new subwoofer models XTDS15 and XTDS18 with a pass-band configuration have been designed both physically and acoustically to reach their maximum efficiency – thus the developed energy peak – around 90 Hz: for this reason, these subwoofers are very compact and “fast” and are designed to achive a higher output/dimension ratio. The crossed internal reinforcement cages make the 15”-thick multi-ply Canadian birchwood cabinet more resistant to the most critical and enduring strains. Each model can be easily stacked both with other unit of the same model, to create vertical subwoofer clusters, and with the associated satellite: the XTD12 model is coupled with the 15” subwoofer and the XTD15 and XTD1015 modules with the 18” one. 6. THE DEFLECTOR PRODUCT RANGE AND RELATED TRANSDUCERS The XTD88 model, like the amplified version XTD88/A, has two 250 W (AES) 8” woofers, with a Neodymium magnet and a 50 W driver, with a Mylar membrane, a 1.4” coil, throat diameter of 1”, with an in-built 1” AWSHTM aluminium horn. The horn dispersion angle is on average 90° horizontal by 40° vertical. The speaker can produce a maximum SPL peak of 129.5 dB. Fig. 6 XTD15 and XTD15/A models The XTD1015 model, like the amplified version XTD1015/A, has a 1000 W (AES) 15” woofer with a Neodymium magnet for low frequencies; a 250 W (AES) 10” woofer with a Neodymium magnet for medium frequencies; a 110 W driver with Polyimide-titanium membrane, a 3” coil, 1.4” throat diameter, and an in-built 1.4” AWSHTM aluminium horn. The horn dispersion angle is on average 90° horizontal by 50° vertical. The speaker can produce a maximum SPL peak of 138 dB. Fig. 4 XTD88 and XTD88/A models The XTD12 model, like the amplified version XTD12/A, has a 700 W (AES) 12” woofer with a Neodymium magnet and a 110 W driver with a Polyimide-titanium membrane, a 3” coil, 1.4” throat diameter, and an in-built 1.4” AWSHTM aluminium horn. The horn dispersion angle horn is on average 90° horizontal by 50° vertical. The speaker can produce a maximum SPL peak of 133 dB. 4/12 Fig. 7 XTD1015 and XTD1015/A models DEFLECTOR LINE The XTDS15 and XTDS18 subwoofers and their corresponding amplified versions both contain a woofer with a 15” Neodymium magnet at 1000 W (AES) for the XTDS15, and 18” 1200 W (AES) for the XTDS18. The maximum SPL peaks are respectively 134 dB and 136 dB. Fig. 8 XTDS15 and XTDS18 subwoofers 7. SYSTEM INSTALLATION 7.1 Ground stacked or suspended installation? There are some arguments in favour of ground installation and some which favour suspended; in both cases there are predominant reasons for using one or the other, depending on practicality. Excluding the possible logistical or visual problems of ground installation, which must be evaluated in each individual case, the positive aspects of ground installation (stacking) are especially associated with the main general coupling of low frequencies with the ground; this makes the low part of the sound spectrum more efficient and, in addition, it gains efficiency and response speed to the low transients. This is also thanks to the fact that the speaker cabinets, which are generally more physically constrained than the suspended ones, are more stable and steady, and avoid turning part of the sound energy into structure movement and losing it as a consequence. Another point in favour of ground installation from the “spatial” and “psychoacoustic” perspectives, is the fact that the sound physically comes from the points close to the stage, and therefore to the music scene. Additionally, for long distance coverage, guaranteeing sufficient SPL (Sound Pressure Level) in the last few rows can lead to excessive SPL in the first ones: in this case, suspension diminishes the SPL gap, therefore distributing sound more evenly, as it reduces the differences in distance from the system of close and long range listeners. 7.2 Angulations Angulations must be managed carefully if more than one Deflector line speaker is to be installed next to the stage. In fact, the high frequencies emitted by speaker horns can cause negative interferences with the others in certain points or spatial directions. One way of checking this phenomenon is by tilting the speakers between them to specific angles, which are calculated knowing the dispersion angle of the sound beam emitted by the single horn; these angles are used to determine both horizontal and vertical tilting. One particular technique is to tilt the two speakers to an angle close to - or not too much lower than - the horn’s dispersion half-angle: by doing this, if the listener moves slightly away from the axis of the system made up by the two coupled speakers, one of the two contributions becomes more negligible than the other, which avoids harmful interference. In the XTD12, XTD15 and XTD1015 models, an appropriate horizontal inclination can be reached by making the countersinks of the “short” parts of the cabinet sides fit together (as shown in figure 10). Fig. 10 Installation with correct horizontal angulations of a cluster of two XTD15 or similar models (XTD12 and XTD1015) Conversely, by bringing the long sides of the speakers closer together, a narrower dispersion angle can be obtained, resulting in a narrower coverage and a longer throw, but with a less harmonized coverage in the nearby field. The choice, therefore, will be guided by the shape and dimensions of the sound recording area. Fig. 9 Stack installation of Deflector speakers The choice of speaker suspension (flying), however, becomes compulsory in all of those cases in which ground installation does not provide the required sound coverage. When the medium-high frequency transducers are not high enough compared to the listeners’ head-level, high frequencies will be poorer even at short distances, due to the sound’s action of “friction” on the public (this being a sound insulation element) and sound refraction phenomena, owing to the vertical thermal gradient created by the public themselves. Therefore, in general, ground installation is of little use to long distance coverage (the problem is reduced in the case of tilted slabs, in which far away listeners find themselves at a slightly higher level compared to those in the first few rows). 7.3 Rigging The XTD12, XTD15 and XTD1015 models are equipped with stateof-the-art flying track hooks, which permit immediate suspension via steel cables, without having to screw extra elements into the cabinet (eye bolts, articulated joints, pins, etc.). The flying track is present in three positions, both on the upper and the lower surfaces of the chassis, allowing the speaker-structure union (or speaker-flying bar) as well as the speaker-speaker connection. Fig. 11 Flying track ring hook (XT-FTH) and its positioning 5/12 User’s manual 8. PASSIVE SPEAKERS: GUIDELINES AND PRECAUTIONS The Deflector Line comes in both passive and amplified versions. The passive version contains crossover filters with equalization and attenuation cells, designed so that transducer channels have a consistent frequency response. This makes it possible, in particular, to attain excellent sound quality of the XTD88, XTD12 and XTD15 speakers, without using an external processor: all plug and go! It is obviously strictly essential to use a processor for the active crossover function in the case of multi-amplification, e.g. with the XTD1015 3-way bi-amplified speaker and with all the complete subwoofer systems. In the latter case, the delay function will also allow correct sound alignment between the subwoofer and the higher modules. However, using the processor is useful in all cases in which the need to protect the speaker is added to the sound quality, exploiting the power output to the maximum, which is really a crucial topic in professional sound recording. In fact, it is important to control the input tension of the amplifiers, so as not to damage the passive components present in the speaker with signals that are too powerful, or otherwise unsuitable for a sound transducer: the following paragraph explains how and why. Beforehand, in other words by operating the amplifier input audio signal, it is clearly not possible to protect the speakers from harmful phenomena coming from the amplifier itself. If an amplifier malfunction generates continuous tension (DC) or at ultra-low frequencies, this can be harmful to the transducers regardless of the input signal. In the same way, high tension peaks, which are caused by switching the amplifiers’ upstream devices on or off, may damage the transducers if the amplifiers are turned on. As a result, while turning on an electro-acoustic system, it is important to switch on the amplifiers only after power has been supplied to the mixer and the control electronics and have stabilized; the opposite sequence must be followed to shut down the system, switching off the power amplifiers first. Therefore, it is recommended control and maintenance of the audio installation and the correct on/off power sequence for the devices present in the audio system. 8.1 Amplification and limitations In general, too much power frequently causes damage to the transducer coil, due to the excessive temperature it produces (high RMS power for long periods), while it only rarely breaks the mechanical part of the cone (membrane or suspensions). In particular, frequencies lower than the reflex tuning frequency may cause excessive excursions in the cone (which is impractical considering the almost non-existent efficiency at these frequencies) with resulting damage. For this reason, it is always advisable to use external processors, which protect the woofer with their frequency cuts and limitations, optimizing efficiency. However, the signal directed to the high frequency drivers in the Deflector line, as in all the other X-Treme models, is protected passively by a special filament device. It is the user’s responsibility not to supply a passive loudspeaker system with signals that harm transducers. For a precise signal management X-Treme recommends using XTDP processors. The purpose of sizing the amplifiers and limiters correctly is to reach the maximum passive speaker capacity without risking damage. In order to have the best performance, i.e. exploiting the transducers to the maximum at the same time as the peaks in the signal, a good practical rule is to have a double powered amplification channel (or over-sized, as we call it) compared to the RMS power tolerated by the transducer. To protect the transducer coil, it is necessary to use a limiter which prevents RMS power from being overused for long periods. This is the function of the limiters in the Deflector series amplified models and the XTDP external processors. Generally speaking, an amplifier whose power is lower than the one tolerated by the transducer (the down-sized amplifier) does not guarantee that damage will not be caused to the transducers, unless a limiter is used. In fact, even an under-sized amplifier, in correspondence with higher input signals, can make the output signal “square” - this means a higher level of power compared to the nominal one of the amplifier and the presence of temporary intervals characterized by continuous tensions, which are particularly harmful to the acoustic transducers. The X-Treme Digital Technology Series class D amplifiers, recommended for amplifying passive speakers, come with an internal limiter (anti clip) which prevents the signal from squaring. Therefore, if under-sized, they are a good guarantee against transducer breakages. However, for the maximum dynamic expression to be reached, as explained above, using over-sized amplifiers is recommended, limiting the input with the XTDP processor limiter functions. If used with Digital Technology Series amplifiers, the correct limiter tools and XTDP processor cuts are included in the official presets set up for such processors by X-Treme Audio. To calculate the limitation threshold if other amplifiers are used, X-Treme provides a “Limiter Calculator” electronic sheet with the processor. 8.2 Presets For external amplification with XTDP processors, X-Treme has provided files with extension .dfa (Device Factory Settings) to be uploaded to XTDP processors, which contain the correct audio parameter tools for each system configuration shown, in the different versions with and without subwoofers. These presets can be downloaded from the www.x-tremeaudio.com website, where the updated version is always available. To be able to use these, it is necessary to make the correct connections between the processor outputs and the amplification channels: see the documentation provided with the processor itself. 8.3 Connections between amplifiers and loudspeaker systems The table sums up the cabling on the inside of the cabinet between the NL4 Speakon connector and the transducers. 6/12 PIN 1- PIN 1+ PIN 2- PIN 2+ XTD88 Full Range Negative Full Range Positive -- -- XTD12 Full Range Negative Full Range Positive -- -- XTD15 Full Range Negative Full Range Positive -- -- XTD1015 Low Freq Negative Low Freq Positive Mid-Hi Freq Mid-Hi Freq Negative Positive XTDS15 Subwoofer Subwoofer Negative Positive -- -- XTDS18 Subwoofer Subwoofer Negative Positive -- -- DEFLECTOR LINE 8.4 Power cables It is essential to use power cables with the correct section. If the cables are too long they will cause significant impedance, which can reduce the audio signal quality and alter the Dumping Factor of the amplifier-speaker coupling. The following table shows the suggested sections based on the length of power cables for various transducer blockages.

GUIDELINES FOR USING ACTIVE SPEAKERS All active versions of the Deflector line contain class D amplifiers and DSP (Digital Signal Processor) with a 24 Bit word code and sampling frequency of 96 kHz. The XTD88/A model has a built-in amplifier of 500 W (@8 Ohm) and a DSP with 2 selectable presets, which can be chosen via a selector switch on the back panel. All of the top models, XTD12/A, XTD15/A and XTD1015/A, are bi-amplified with an 800 + 800 W (@8 Ohm) class D amplifier and a DSP with 4 selectable presets, which can be set using 2 switches on the back panel. The same electronic equipment is present in active subwoofers, whose double amplifier is used in “bridged-mono” function for a single amplification channel of 1600 W in total (@16 Ohm). The DSP of every single module has been programmed in the factory, where crossover cuts, delays, equalizers and limiters, depending on the frequency, have been set up on each preset, which can be selected by the user. All of this aims to create the best sound with maximum SPL expression, with the complete assurance that the amplifier or the speaker itself will not be damaged. The back panel has an XLR type balanced input with direct link to the output, Neutrik PowerCon input for power supply and related loop output, volume control and the two switches for preset selection. One LED signals the power status, and another one indicates the in signal presence (with a green light) and indicates the limitation threshold (with a red light). In order to reach the maximum SPL without compromising the dynamic quality of the signal, the red light must come on intermittently and not continuously.

The first three correspond to different equalizations, which can prove to be more suitable for reproducing sound support or amplifying “live” sources. The “sub” preset corresponds to “music” equalization, with a more selective high pass cut, suitable for coupling with the pertinent Deflector subwoofer. To provide an example, the figure shows the frequency responses1 of the four XTD15/A speaker presets. Fig. 13 XTD15/A satellite presets measured on the ground with reflective floor and microphone along the axis of 2 m in virtually anechoic conditions (measurement of impulse response and separation of reflections, the first obstacle at 4 m). Input signal – 20 dBu. 1 Fig. 12 Details of the rear panel of XTD12/A, XTD15/A and XTD1015/A 7/12 User’s manual Fig. 14 Details of XTDS15/A and XTDS18/A rear panel The two switches on amplified subwoofer modules XTDS15/A and XTDS18/A make possible the following operations: two different low pass cuts and polarity inversion. The lowest frequency cut (90 Hz) is adapted correctly to the use with the respective main modules in the Deflector line, which must be set to “sub” mode by choosing the correct preset; the other cut (120 Hz) can be useful if used with the respective Deflector Line main modules, in order to create a boost wherever necessary in the 100 Hz zone, or to use the subwoofers with smaller main modules, which are not extended so well at low frequencies. The figure shows the subwoofer model XTDS18/A frequency response2 as an example, with the two different low pass cuts available. Fig. 16 Standard configuration of subwoofer-upper module coupling (direct polarity). 10. SYSTEM CONFIGURATIONS The following are the standard Deflector range configurations. In each case it is also possible to use the “halved” version, with just one satellite and one subwoofer on each side (consequently halving the sound power supplied). The connections of two loudspeaker systems to the same amplification channel should be in parallel. The amplifier supply remains unchanged when going from one to two speakers at each side, because halving the acoustic impedance from 8 Ohm to 4 Ohm allows the amplifier to generate about twice as much power, in other words its rated power. Fig. 15 Subwoofer XTDS18/A presets measured on the ground with reflective floor and microphone along the axis of 2 m in virtually anechoic conditions (measurement of impulse response and partial separation of reflections, the first obstacle at 4 m). Input signal – 20 dBu. 2 In standard insulation conditions (with the main speakers resting on the subwoofers, directly or with a stand holder), the polarity must be rigorously set to direct mode, therefore with the switch turned off. For this reason, the position with inverted polarity (switch down) is marked in red on the panel in this particular case. Otherwise there will be a pressure cancellation effect, that will lead the device to loose efficiency in the crossover band (100 Hz zone). Polarity inversion can only allow for a better subwoofer and upper module coupling only, if the two cabinets are placed between them. “Better coupling” means that in the crossover band (100 Hz zone) the system is able to supply more sound power in the environment, which depends on the relative position between the subwoofers, upper modules and the walls or large obstacles. Whether or not polarity inversion brings about this improvement can be understood by listening, through direct measurements or simply “by ear”. 8/12 Fig. 17 System configuration with XTD88 and XTDT amplifiers DEFLECTOR LINE Fig. 18 Deflector 2-way type alpha system configuration (with XTD12/A and XTDS15/A) Fig. 19 System configuration with XTD15/A and XTDS18/A Fig. 20 Deflector 3-way type alpha system configuration (with XTD1015/A and XTDS18/A) 9/12 User’s manual Fig. 21 Deflector 2-way type beta system configuration (with XTD12 and XTDS15, XTDT amplifiers and XTDP26 processor) Fig. 22 System configuration with XTD15 and XTDS18, XTDT amplifiers and XTDP26 processor Fig. 23 Deflector 3-way type beta system configuration (with XTD1015 and XTDS18, XTDT amplifiers and XTDP26 processor) 10/12 DEFLECTOR LINE For a no-compromise dimensioning of the power supplied to the subwoofers, X-Treme Audio also proposes the following special configuration with transducers of 4 Ohm and amplification of 1500 W (@ 4 Ohm) per channel, which are obtained using a XTDT6000F amplifier. This configuration can replace the subwoofer section in all the proposed configurations above. Fig. 24 Special system configuration with 4 Ohm subwoofer Here are two more configurations, both set up with the X-Treme “Big punch” subwoofer in order to reach maximum performance at low frequencies. The coupling of two transducers and the increasing total cabinet volume give the system greater low frequency extension and higher overall efficiency, for a more powerful and vivid listening experience.
