Extended Range Loudspeakers Special Duty Loudspeakers ii I\ & * 2145 300-mm (12-in) Composite An integrated system consisting of a 300.mm (Gin) low frequency loudspeaker, separate 50-mm (2.in) high frequency direct radiatorand 3-kH2 frequency dividing network Often used as a monitor system in limited space applications. its frame is shallow enough to allow installation within wall or ceiling structures for distributed music and paging systems. 2150 380-mm (15-in) Composite Ideally suited for maximum intellrgrbrlrty,high level paging systems and distributed reinforcement in large areas. It consists of a 380-mm (15-in) low frequency loudspeaker and a 130.mm (5-in) direct radiator integrated on a singleframe.The 2150 may be installed in ported enclosures or in a 4530 low frequency horn. [The 3125, a 1200.Hz network, is optional.) 2105 130-mm @-in) Speech Range A powerful midrange loudspeaker providing high acoustic output, smooth response and wide drsperston Well suited for in-line arrays and distributed cerlrng installations for naturolsounding paging systems or limited bandwidth musrc reproductionThe 2105 is also useful as a midrange dnver in medium efficiency monitor systems. 2115 200-mm (a-in) Full Range Natural wide-range performance with peakfree response and freedom from distortron through more than eight octavesThe 2115 can be used in distributed systems as a single-unit monitor or in column array for moderate level, high quality reinforcement SpewI JBL Professional Series extended range loudspeakers are rugged, precrsion transducers for use in custom ltne arrays, distributed source installations and general applrcatrons. Frequency range extending through the major portion of the audio spectrum allows their use as single-driver systems, for reproduction of the extreme high frequencres each may be augmented by a compressron driver equrpped with the appropriate horn and acoustic lens These drivers incorporate precisely machined. highly efficient magnetic assemblies, large edgewound alumrnum voice coils. and shallow. curvlllnear cones Pneumatrcally formed alumrnum center domes provrde high frequency reproduction Duty Loudspeakers 2105 Nominal Diameter 130mm 2115 5 in 200 mm B I” 2145 Nominal Impedance 8n 80 or l&l 8n sensltlvlty’ Power Capaclh/ (Continuous Program) 4ow 1 W. 1 m 1 mW, 30 R Frequency Range (3.3 It) (9.1 ml 95 dB 46dB 150Hz-15kHz 4ow SFI 92 dB SPL 43 dB 35w SPL 92 dB SPL 43 dB SPL 300 mm 12in _____________________---_-------___--________~~~______----------- Low Frequency High Frequency 2150 Bfl 380 mm “C i^ 14 I/\ Htgh Frequency 130 mm 5ow IOOdB 51dB sn _ Net Weight 2% lb 1.65T (16.500 gauss1 6 litres 0.2 ft’ 76 mm 3x I” 1 4 kg 3 lb Aluminum 3 kg 6% lb 0 85.T (6500 gauss) 28 -56 lltres 1~2rt’ 98 mm 3x I” 3.6 kg 8 lb 76 mm copper 3 kg 6%lb 57-85 lltres 2.3flJ 111 mm 4% in 4.3kg 9%lb ;1’,.000 gauss1 16mm W in Copper 0.7 kg l%lb 1.2T (12.000 ga”ssJ 102 mm * in copper 5.7 kg 12%lb 1.15T II 1.500 aaussi 169 i1tres 6 flJ 146 mm 5% I” 7.2 kg 15Wlb 22 mm copper 12 kg 2X lb 1657 (16 500 gauss] 200Hz 22 mm copper 55 Hz 51 mm 2 in 40 Hz 15 kHz 50Hz-12kHz 1.2 kg 30 Hz SPL SK Depth Voice Coil Mctwol 50 mm 2 in Low Frequency Recommended EllCIOS”KZ?
