Great things really do come in small packages! This

ultra compact in–wall speaker system is designed to

virtually disappear in any room. A rugged 2" full range

driver is mounted in an attractive rectangular faceplate

that is the same size as a standard wall switch. In fact,

this unit actually mounts in a single gang electrical box

or low voltage bracket (both sold separately). When

used alone, it is perfect for voice reproduction in public

areas, on kiosks or retail displays. It is perfectly suitable

to mount these speakers at wall switch or AC outlet

height.

As mentioned above, this speaker mounts exactly the

same as any single gang electrical device. It may be

mounted in an electrical box or low voltage bracket.

Note: As this is considered a low voltage device, this

unit may not be mounted in the same electrical box as

AC powered devices. Additionally, when routing

speaker wire, it may not pass through the same hole in

studs as AC wiring.

Attached to the rear of the speaker are two conductors

of 22AWG speaker wire. Note that the (–) lead

connects directly to the speaker. The (+) lead connects

to the capacitor. When installing multiple speakers in a

distributed sound system, it is important to keep the

+/– wiring consistent to keep the speakers in phase.

This will ensure proper imaging and maximum low

frequency response.

Installation

Overview

For home theater and music applications, a subwoofer

is required, as the low frequency response of this unit

drops substantially below 300Hz.

This speaker comes equipped with an attached 66µF

filter capacitor, which prevents frequencies below

300Hz from reaching the speaker. It is important not to

remove this capacitor, as distortion will be created with

this speaker attempts to reproduce low frequencies.

With this capacitor in place, the overall power capacity

of the speaker is greatly increased.

Additionally, running speaker wire and AC wire in a

parallel arrangement over long lengths should be

avoided. If AC wiring and speaker wiring must cross

paths, it is best if they cross at 90 degree angles to

each other, thus keeping the contact area between the

two at a minimum. These practices are important

when keeping potentially induced noise at a minimum.

Only properly rated CL2 or CL3 in–wall speaker wire

should be used in these applications. It is

recommended that at least 16AWG wire be used with

this product. Additionally, local codes may exist

regarding such installations. It is the responsibility of

the installer to be aware of said codes when installing

this equipment.
