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 tr apezoidal enclosures are capable of extremely high sound pressure

levels and exceptional sonic quality with wide dynamic range and bandwidth.

Both ser ies 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 tonameafew.

In creating the LX Ser ies, we set some basic parameter s 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 ever y audio challenge .

NEW LOOK, DISTINCTIVE FEATURES, HIGH STANDARD,

GREAT POWER AND MORE CHOICES.

Elliptical Wave Guide Horn (1.4” Exit)

In compar ison to a conventional rectangular hor n, the elliptical

Wave Guide offers superior control over HF coverage ,

with reduced distor tion, 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”) true compression driver designed

specially for the LX and LX-E Series. This titanium

diaphragm dr iver features a 1200g-magnet with a

35mm (1.4”) exit for br illiant, natur al HF

reproduction.

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 networ ks that allow a four-box system to be powered by one amplifier.

Tr a pezoidal, Plywood and Composite Construction

The LX-E’s cabinet is constructed from plywood on all critical surfaces (where durability

is impor tant) and wood composite where resonances need to be kept to a minimum.

The trapezoidal shape further improves sonic accuracy by significantly reducing inter nal

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 ar rayed. The

LX-12E and LX-15E are fitted with these flying inser ts.

Protective Finish

The LX is all finished using a tough, black industr ial 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 inter nal 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 comfor tably, therefore making them easy

to move. Built-in castors are available on some larger units for ease of transportation.
