Due to demand from consultants nationwide specifying the popular Impulse 2414 stairstep loudspeaker in new construction—particularly poured-concrete construction in stadiums and large churches—Architectural Acoustics has developed an all-steel back box specifically for this loudspeaker.

Contractors can now install the back box prior to the concrete pour or before the stairs or walls are closed up and return later to install the speaker itself. This avoids the possibility of cosmetic damage to the loudspeaker or theft during the construction phase.

Multiple knockouts on the top, bottom and sides of the back box allow for easy and flexible signal cable routing. Additionally, the box is designed with added rear depth for the installation of a transformer for 70 Volt or 100 Volt applications. The back box is constructed of zinc chromatecoated steel in order to reduce the possibility of rust in outdoor environments or when exposed to the corrosive chemicals in wet concrete. The Impulse 2414 loudspeaker mounts into the front of the back box for a very simple, fast and clean-looking installation.

This U.S.A.-made back box is now in stock and shipping. Please contact Architectural Acoustics for further information and pricing.
