Turbosound TXP-151 User manual

adjustable gain control, power LED, and
signal and limit LEDs. Balanced 3-pin XLRs
provide input and link out connections from
mixing consoles and to additional powered
TXP enclosures. A two-stage high-pass filter
is user-selectable for stand alone use, or for
correct integration when used with a
subwoofer. Mains power is supplied via an
IEC mains connector with integrated
fuseholder.
The trapezoidal cabinet is constructed from
15mm (5/8”) birch plywood, and the
symmetrical 45° angled sides enable its use
as a compact wedge monitor. A dual angle
pole mount socket is fitted for FOH 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 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 TXP-151 to
be suspended in permanent installations.

Corporate rental
The TXP-151 is a compact trapezoidal self-powered
two-way loudspeaker enclosure designed for use in
a wide variety of live sound, corporate rental and
mobile DJ applications that require professional
sound quality in an easily transportable format.
It consists of a 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, together with an
integrated Class D amplifier module.
The Class D amplifier delivers abundant
power to the drive units, separating the
frequency bands via a passive crossover
network, with optimum headroom being
governed by the built-in fast acting limiter
circuits.
The crossover incorporates a two-stage
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.
All operating controls and indicators are
provided on the rear panel, including

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.

INSTALLATION AND
RIGGING HARDWARE
The enclosure is fitted with a dual angle pole mount socket, allowing the cabinet to be
mounted on a straight pole over a bass cabinet, or alternatively on a 35mm speaker stand,
either vertically or raised higher and angled downwards in order to improve audience
coverage.
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 using M10 shoulder eyebolts with
a minimum thread length of 20mm. The single back panel rigging point is used to set the
desired downward inclination.
The PB-55 pole bracket allows cabinets to be wall mounted in permanent installations with a
range of adjustment angles.

input, shall be flat within ±3dB from 100Hz to 18kHz, and within ±10dB from 40Hz to 20kHz
(full range), within within ±3dB from 125Hz to 18kHz, and within ±10dB from 100Hz to 20kHz
(high pass). Nominal dispersion, at -6dB points, shall average 70°H x 40°V. Maximum SPL
(peak) measured with music program at stated amplifier input shall be 130dB. Dimensions:
652mmH x 472mmW x 408mmD (25.7”H x 18.6”W x 16.1”D). Weight: 28.1kg (61.8lbs). The
loudspeaker system shall be the Turbosound TXP-151. No other loudspeaker shall be
