Overview:

The 8138 is an 8" ceiling speaker

designed for use with a pre-install in-

ceiling backcan, resulting in high-

fidelity performance at a cost-

effective price point. The 8138 is

ideal for a wide variety of

commercial sound applications from

restaurant and retail to professional

offices and reception areas.

The built-in 6 Watt transformer

allows use on 70V or 100V

distributed speaker lines. High

sensitivity of 97 dB delivers

maximum sound levels using minimal

amplifier power, allowing the use of

smaller power amplifiers compared to

when using lower sensitivity drivers.

The driver features a 25 mm (1 in)

voicecoil with Kapton coil former for

reliability. The treated cloth surround

provides deeper bass response

compared with typical paper-roll

surrounds, for fuller sound quality.

The 8138 fits the MTC-81BB8

backcan and MTC-81TB8 tile bridge,

or can be used with most in-ceiling

backcan/tile bridge systems designed

with four mounting points on a 286

mm (11¼in) diameter mounting

circle.

With its contemporary grill design,

the 8138 provides a stylish upscale

look that fits into many decórs. The

8138 brings style and performance to

basic commercial sound systems.
