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.

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.
