LX & LX- E Series Professional Loudspeaker System
NEW LOOK, NEW FEATURES, NEW STANDARD, MORE POWER AND MORE
CHOICES……
Designed to cater for those who want more power than the highly successful EVP
ranges can offer, the LX and LX-E use superior Wharfedale components to offer a range
of higher power, higher performance speakers that includes full range units, stage
monitors and subwoofers - making it easy to create a system from the models available.
So what’s different about the LX and LX-E Series?
Designed from the ground upwards the LX and LX-E range feature new custom components in
every cabinet. New woofers, larger format compression drivers and an elliptical wave guide
horn have all been developed from scratch to offer performance and features that are usually
only found on cabinets with a much higher price tag than the LX and LX-E.
In creating the LX Series, we set some basic parameters to design a range that delivers without
exception the performance, features and quality that our customers demand. We also kept it
simple; the LX-E range has a ‘systems’ approach, a range of models that can be used together
to provide solutions for nearly every audio challenge.
In LX series, the powerful LX-15B, LX-18B, LX-18MB and LX-218B sub bass systems have
been designed for use with large-scale LX-12, LX-15 and LX-215 systems to extend the total
LF output power.
In demanding professional applications, the LX-15B and LX-18B, which feature an internal
two-way network, allow the four-box system to be powered by one amplifier. Tough industrial
carpet covering provides durability and protection, and contributes to the overall safety in the
set-up and use of the LX systems.
The LX-E Series has the same model line up as the LX Series. The LX-E is finished in a
hardwearing, two-stage epoxy black paint finish and is constructed from premium grade
plywood for extra strength. Among the whole series, the LX-12E and LX-15E have multiple
mounting points for maximum flexibility when installing.
In comparison to the LX Series, the LX-E also has a greater power handling capability.

FEATURES

compression under extended high power use.
•Heavily braced enclosure

Titanium 50mm diaphragm, 1.4” exit compression driver
This unit features a larger magnet, increased power handling and a 1.4” (35mm) throat exit,
allowing a lower crossover frequency to be used, resulting in smoother, more controlled HF
and therefore better vocals.
Large magnet structures and tight construction tolerances give accuracy, high efficiency and
reliability.
Large wave guide elliptical horn:
The benefits of this elliptical Wave Guide, featured in all the LX & LX-E series full range
models, is that compared to conventional rectangular horns, the elliptical Wave Guide offers
superior control over HF coverage, with reduced distortion, greater output and smoother
frequency response.
The elliptical shape of the horn means that there are no corners or parallel surfaces to distort,
diffract or reflect the sound – therefore the output is smoother, cleaner and more consistent,
again resulting in a superior vocal sound.
Large Wave Guide elliptical horn provides superior control over HF coverage.
Custom cast frame woofers:
The woofers have been designed and built specifically for the LX & LX-E enclosures – they are
not old designs housed in new cabinets. The increased power handling and durability of the
LX & LX-E are due to the new drivers featuring larger voice coils with extended excursion
capability coupled with a new aluminium cast frame.

ProTech™ Driver Overload Protection System
Understanding that sound systems are often asked to perform beyond their original design
parameters, we have designed a smooth, progressive dynamic limiter/protection system that is
carefully tailored to each model. Overloads are limited and drivers are protected against long
term transient or peak conditions. The ProTech™ system progressively converts excess power
to heat and triggers a reduction in power to the HF drive. When the overload condition is
removed the system returns seamlessly to normal operation.
Sophisticated Crossovers Design
Each crossover in the LX and LX-E Series is built using the highest quality components and
designed specifically for that system, enabling smooth power and frequency response control
through crossover region. The LX-15B and LX-18B feature integral two-way networks that allow
a four-box system to be powered by one amplifier.
Trapezoidal, Plywood and Composite Construction
The LX-E’s cabinet is constructed from plywood on all critical surfaces (where durability is
important) and wood composite where resonances need to be kept to a minimum. The
trapezoidal shape further improves sonic accuracy by significantly reducing internal flutter
echoes and standing wave resonances that are often apparent in rectangular shape cabinets.
Trapezoidal designs allow more compact arrays and sonic accuracy.
Mounting points:
For maximum flexibility when installing, we have designed two specific models which feature 12
x M10 rigging points allowing the cabinets to be flown or arrayed. The LX-12E and LX-15E are
fitted with these flying inserts.

Protective Finish
The LX are all finished using a tough, black industrial carpet offering exceptional protection and
durability for life on the road. The LX-E is coated with Duraguard™, an abrasion resistant paint
that creates a protective ‘skin’around the cabinet. Both finishes contribute to the overall safety in
the set up and use.

Strong Grille, Square Handles and Castors
In order to provide maximum protection to the internal components of the loudspeakers, the front
grilles are full steel with 1.5mm thick. The square handles design allows the cabinets to be
gripped securely and comfortably, therefore making them easy to move. Built-in castors are
available on some larger units for ease of transportation.

PRODUCT PAGES
The LX and LX-E series of loudspeakers each consist of nine models in total, comprising five full
ranges multipurpose systems (with FOH and monitor systems in both 12 inch and 15 inch
versions), and four sub bass cabinets (in both 15 inch and 18 inch versions).
