bi-amped, active loudspeaker system

W18As

The trapezoidal enclosure design is based on solid technical reasons:

• directivity remains constant and controlled, even when two or more

enclosures are installed side by side.

• the problems related to interferences and irregularities in frequency

response and directivity, typically encountered when using multiple

enclosures, are thus dramatically reduced.

Multiple enclosures arrays can be assembled for wide dispersion and/or

long throw.

Description

Introduction

The 2-way bass reﬂex enclosure incorporates:

■ custom designed, high quality components.

■ 2 ampliﬁers:

600 + 250 W continuous

850 + 350 W peak

■ 2 independent processors

■ 24dB/Oct electronic crossover

The bass reﬂex enclosure, constructed from birch plywood, is

equipped with a custom designed 18" low frequency woofer

and a 2" driver with constant directivity horn for the mid/high

frequencies, each driven by its own dedicated power ampliﬁer.

A high slope 24dB/Oct. electronic crossover and two processors

(one for each ampliﬁer) optimize the dynamic range and

frequency response of the system, while protecting the drivers

from thermal and electrical overloads, resulting in increased

reliability and outstanding performance.

Its adaptability to various applications allows the W18As to

be used in any type of installation ensuring optimum results

to any professional requirement for sound reinforcement and

distribution.
