Superb Performance

VLS 7 (EN 54)’s design comprises 7 vertically arrayed 3.5″ fullrange drivers for high intelligibility speech reproduction from 110 Hz – 14 kHz (-10 dB) with 118 dB peak SPL (1 m, Lo-Z). The UV and weather resistant aluminium enclosure provides 130° horizontal x +6° / -22° vertical dispersion for targeted coverage. Also certified for water and dust ingress protection to IP65 standard, the VLS 7 (EN 54) is an exceptional choice for challenging environments such as indoor swimming pools, saunas, or work areas with unusually high levels of dust or moisture, and numerous outdoor applications.

FAST – Focused Asymmetrical Shaping Technology

Designed with an asymmetrical vertical dispersion pattern, the VLS 7 (EN 54) merges enhanced performance with simplified mounting to cover a wide range of installed applications. The vertical dispersion of the VLS 7 (EN 54) allows optimal zones to targeted for even and precise coverage. Additionally, in installations where conventional column loudspeakers require substantial downward tilt, the VLS 7 (EN 54) requires much less – even enabling flush mounting, for significantly improved visual aesthetics.

Low-Z or Transformer Operation

A multi-position EN 54 compliant tamper-resistant rotary switch on the rear panel allows the choice of either the low-Z, or the 70 / 100 V operating modes, with available transformer taps at 150; 75; 37.5; 19; 9.5, and 5 Watts.

Outdoor Applications

A right angled water tight cable gland is supplied with the VLS 7 (EN 54) for use in outdoor applications with an input panel cover is secured to the cabinet using the four screws. Simply pass the wiring through the cable gland and make your connections on the provided barrier strip. A second strip is provided for linking additional loudspeakers in either low-Z, or 70 / 100 V distributed systems.

Attractive & Easy to Install

The stylish and durable extruded aluminium enclosure with stainless steel grille features a semi matt black paint finish that fits unobtrusively into even the most architecturally sensitive environments. Input is via a low insertion loss 150 W line transformer with multiple taps for 70 / 100 V line systems. A dedicated flying bracket, wall mount bracket, input panel cover plate, and weather resistant gland are all included for ease of installation. At only 10.8 kg (23.8 lbs), the VLS 7 (EN 54) is significantly lighter and easier to install than many competing products.


Utilising a pair of internally paralleled barrier strip connectors, the VLS 7 (EN 54) can either be connected to a low-Z amplifier, or used within a 70 / 100 V distributed system. The operation mode is easily selectable via a single switch located on the rear of the enclosure.

Build Quality

The architecturally styled corrosion resistant extruded aluminium enclosure is finished in a semi matt black paint and is complemented by a stainless steel perforated grille. All VLS 7 (EN 54) mounting hardware is included and over-engineered for the ultimate in safety.
