The TXD-151 is a trapezoidal passive two-way loudspeaker enclosure designed for use in a wide variety of live sound, fixed installation and mobile DJ applications that require professional sound quality in an easily transportable format. It consists of an 15” reflex-loaded low
frequency driver and a 1” high frequency compression driver on a 70°H x 40°V
dispersion HF horn in an optimally tuned trapezoidal enclosure. These high grade
components are matched with an internal passive crossover to ensure a seamless
transition between the HF and LF drivers.
The crossover network incorporates a twostage thermal overload protection system which prevents damage to the high
frequency driver, reacting instantly to large transient peaks while still allowing wide
dynamic range to be maintained. Although the protection system is transparent at normal operating levels, as the level
increases the signal is gradually and
imperceptibly compressed once the critical threshold has been reached.
TXD-151
The cabinet is constructed from 15mm (5/8”) birch plywood, screwed and glued together for maximum rigidity and is finished as
standard in semi-matt textured TurboBlue™ paint. A pole mount socket is fitted for use
with optional 35mm poles and loudspeaker stands. Two recessed flush handles are
provided for easy lifting and carrying, and
four rubber feet are fitted to the bottom of the cabinet. A grey powder-coated
perforated steel mesh grille protects the drive units from damage.
Rigging points are provided on the top and
rear of the cabinet to enable the TXD-151 to be suspended and angled in permanent
installations using shoulder eyebolts. M8
rigging points are provided on the rear of the cabinet for use with Turbosound wall and ceiling brackets.
Two Neutrik Speakon NL4MP speaker
connectors are located on the rear panel,
providing input and parallel connections to additional TXD series cabinets.

Impedance A constant current circuit was used to measure the impedance. Frequency response The frequency response shown was obtained by feeding a swept sine wave through the system in a half space environment. The position of the microphone was vertically on-axis at a distance of 2 metres, then scaled to represent 1 metre. 2nd & 3rd Harmonic Distortion Distortion measurements were obtained using an Audio Precision harmonic distortion analysis system and comply with AES recommendations for enclosure measurement (AES paper ANSI S4-26-1984). Data Conversion All graphs were digitally generated using the APEX custom software system, designed to translate data derived from Audio Precision ‘System One’ test equipment into AutoCAD™. This program enables graphical information to be plotted to a high degree of accuracy.

TXD-151 INSTALLATION AND RIGGING HARDWARE
T X D S E R I E S E N G I N E E R I N G I N F O R M AT I O N The enclosure is fitted with two M10 rigging points on the top and one on the back, to allow
single loudspeakers to be rigged in permanent installations suing M10 shoulder eyebolts with a minimum thread length of 20mm. The single back panel rigging point is used to set the desired downward inclination.
M8 rigging points are also provided on the back panel to enable fixed installation use with the WB-66 wall bracket, CB-55 ceiling bracket and PB-55 pole bracket.
