LX and LX-E SERIES PROVIDE EXCELLENT SOUND
PROJECTION, VOCAL PERFORMANCE AND BALANCED
MUSICAL REPRODUCTION

In the 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 LF output power.

In demanding professional applications, the LX-15B and LX-18B, which feature an
internal two-way network, allow a 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 the same power ratings.

forefront of loudspeaker technology –
these seventy years of experience in
the design and manufacture of audio
systems make Wharfedale Pro products
second to none.

We put in a lifetime of experience –

EXTENSIVE LX & LX-E SERIES COVER THE HIGH-
PERFORMANCE SPECTRUM

The new LX and LX-E Series of loudspeakers each consist of nine models in total,
comprising five full ranges (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).

Boasting distinctive style and features, these high powered, high performance
arrayable trapezoidal enclosures are capable of extremely high sound pressure
levels and exceptional sonic quality with wide dynamic range and bandwidth.

Both series have been developed with exceptional features including the large
elliptical Wave Guide horn, the use of cast-fame, large voice coil woofers for
sustained output capability and minimal power compression under extended
high-power use, and the ProTech™ protection system designed to protect the
HF unit, just to name a few.

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.

NEW LOOK, DISTINCTIVE FEATURES, HIGH STANDARD,
GREAT POWER AND MORE CHOICES.

Elliptical Wave Guide Horn (1.4” Exit)

In comparison to a conventional rectangular horn, the elliptical
Wave Guide offers superior control over HF coverage,
with reduced distortion, greater output and smoother
frequency response. The elliptical shape 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, due to
the elliptical shape, mid to high frequencies are
diffused more efficiently.

Titanium 50mm Diaphragm, 1.4” Exit Compression Driver

The elliptical Wave Guide horn is coupled with a
50mm (2”) tr ue compression driver designed
specially for the LX and LX-E Series. This titanium
diaphragm driver features a 1200g-magnet with a
3 5 m m ( 1 . 4 ” ) e x i t f o r b r i l l i a n t , n a t u r a l H F
reproduction.

With enclosures built from a
combination of particle and MDF
in a black carpet finish, the LX is
ideal for use in live sound
applications.

With enclosures built from
plywood in a black paint finish, the
LX-E has extra features to make it
more suitable for the installation
market.

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).

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 driver. 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 the 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.

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 is 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 and 1.5mm thick. The square handles allow
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.
