Delivers Clear, High-fidelity Sound The JBL 8128 delivers top-notch sound in a wide array of commercial sound applications. This in-ceiling loudspeaker houses a full-range 8-inch driver, exhibiting a lofty 50Hz–16kHz frequency range and a room-filling 90° of conical coverage. Beyond that, the 8128's high sensitivity ensures maximum power efficiency. You also get 70V/100V taps for use with high-impedance systems, along with standard 8-ohm setups. Here at GearNuts, we've found the 8128 a breeze to mount, thanks to its dog-ears for easy blind-mount installations. What's more, this loudspeaker's open-back design also enables you to use it in applications that don't require an in-ceiling backcan. The JBL 8128 is a terrific choice for restaurant and retail settings, professional offices, reception and waiting areas, and any other situation that requires clear, high-fidelity sound in an unobtrusive form factor.JBL 8128 8-inch Full-range In-ceiling Loudspeaker Features: Full-range 8-inch driver exhibits a 50Hz–16kHz frequency range 90°
