FEATURES
• Superb audio quality: carefully designed and matched loudspeaker drive units are used
to give
you exceptional performance and many years of reliable, trouble free operation.
• High quality loudspeaker components are used throughout the range. Low frequency
drivers are specified for high sensitivity and durability, while high frequency drivers are
selected for consistent and reliable performance.
• High frequency protection system: two-stage thermal overload circuits operate on all
two-way products to prevent damage to the HF drive units from both transient peaks and
long term heating effects.
• Professional appearance: TXD series enclosures are equally suited to live sound and DJ
applications as well as permanent installations.
• Easy transportability: comfortable, ergonomic flush handles are provided on all TXD
series enclosures for easy lifting and transportation in mobile sound reinforcement
applications.
user manual
TXD series
• Wide dispersion: TXD series enclosures are designed to give wide and even dispersion
patterns in order to maximise sound coverage over a given area from single
loudspeakers.
• Solid construction: all Turbosound TXD series cabinets are built from high grade, multi-
layer birch plywood and are finished in a durable semi-matt textured paint.
• Integral rigging points: fitted as standard, enabling use with optional M10 shoulder
eyebolts for many types of fixed installations. TXD-081, TXD-121 and TXD-151 enclosures
can be permanently installed using Turbosound wall and ceiling brackets. All models are
type-tested for load rating to ensure safe rigging.
• Pole mount and tripod stand use is facilitated by the provision of integral pole mount
fittings.
• Speakon NL4MP connectors are fitted to all TXD series enclosures, enabling simple and
easy hook-ups as well providing loop-in / loop-out facilities to additional enclosures.

PRODUCT RANGE SUMMARY
TXD-081
The TXD-081 is a compact two-way loudspeaker recommended for portable speech and music
reinforcement in an easily transportable cabinet, as well as fixed installation applications requiring
professional quality background sound.
It is an all-passive design featuring an 8” low frequency driver and a 1” high frequency
compression driver on a 100ºH x 60ºV Converging Elliptical Waveguide™ HF horn. The drive units
are matched with an internal passive crossover network to ensure a seamless transition and these
are all housed in an optimally tuned trapezoidal birch plywood enclosure.
The compression driver is protected from accidental damage due to overdriving by an intelligent
protection circuit built into the crossover network which detects signal level, and automatically
attenuates should it approach or exceed potentially damaging levels.
The TXD-081 is equipped with internal rigging points for use with Turbosound wall and ceiling
brackets, and M10 eyebolts. A standard 35mm pole mount is fitted.
The rear panel carries dual Neutrik Speakon NL4MP speaker connectors for input and parallel
connections to an additional TXD series cabinet, or TXD series bass enclosures.
TXD-121
The TXD-121 is a compact 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 a 12” reflex-loaded low frequency driver and a 1” high frequency compression driver
on a 70ºH x 40ºV dispersion HF horn in an optimally tuned trapezoidal enclosure. These highgrade components are matched with an internal second order passive crossover network to
ensure a seamless transition between the HF and LF drivers.
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. 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.
The cabinet is constructed from 15mm (5/8”) birch plywood, screwed and glued together for
maximum rigidity. 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 drivers from damage.

M10 rigging points are provided on the top and rear of the cabinet to enable it 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 or bass enclosures.
TXD-151
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 a 15” reflex-loaded low frequency driver and a 1” high frequency compression driver
on a 70ºH x 40ºV dispersion HF horn in an optimally tuned trapezoidal enclosure. These highgrade components are matched with an internal second order passive crossover network to

TXD series
passive crossover network also protects the high frequency compression driver from being
overdriven.
The TXD-252 is ideal live music in bars and pubs, or for installing as a permanent system for pubs
and clubs. It can be suspended vertically, or horizontally with the HF horn rotated, using the M10
rigging points. Due to the trapezoidal cabinet shape it can be positioned close to a ceiling where
space is limited.
