The JBL 8138 is an 8" ceiling speaker designed for use with a pre-install in-ceiling back-can, resulting in high-fidelity performance and 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 it to be used 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) voice-coil 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 back-can and MTC-81TB8 tile bridge, or can be used with most in-ceiling back-can/tile bridge systems designed with four mounting points on a 286 mm (11-1/4") diameter mounting circle. With its contemporary grill design, the 8138 provides a stylish upscale look that fits into many decors. The 8138 brings style and performance to basic commercial sound systems.
