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 Wharfed ale components to offer a r ange
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 comp onents 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.

FEA TURES

distortion, greater output and smoother frequency response

• Cast frame, large voice coil woofers for sustained output capability and minimal power
compression under extended high power use.

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 enclosure s – 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.
