About: JBL 8138 8in Full-Range In-Ceiling Loudspeaker for Pre-Install Backcans (Each)

The 8138 8" ceiling speaker is 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 (111⁄4 in) 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.
