Pair of In-Ceiling Speakers for Home Theater

This pair of in-ceiling speakers is built for stereo or surround sound in a home theater or whole-house audio system. They connect to any receiver or amplifier that has raw speaker wire outputs. The passive design means no separate power supply is needed. Buyers who want active speakers with built-in amplification or wireless streaming will need a different solution.

Pressure Lock Mounting with Paintable Grilles

The Pressure Lock Mounting System clamps the low-profile housings to drywall without separate hardware. A round cut-out of 6.61 inches and a mounting depth of 2.8 inches are required. The overall diameter is 7.48 inches. Durable ABS housings and removable grilles can be painted to match the ceiling. Installers who need a rectangular cut-out or a different mounting depth cannot use this system.

5.25 Inch Woofers and Pivoting Titanium Tweeters

Each speaker uses a 5.25 inch woven fiber cone woofer with a butyl rubber surround and a pivoting titanium tweeter in a 2-way configuration. Frequency response is 40Hz to 22 kHz with a sensitivity of 97dB at 8 ohms. The amplifier must deliver between 10 and 250 watts per channel. Listeners who require deeper bass extension below 40Hz will need a separate subwoofer.

Questions about this item

What amplifier power range does the 97 dB sensitivity at 8 ohms require?

The speakers need an amplifier delivering between 10 and 250 watts per channel to match the 97 dB sensitivity at 8 ohms.

What ceiling cut-out diameter and mounting depth does the 7.48" overall speaker need?

Cut a 6.61" round hole and ensure at least 2.8" of clearance above the ceiling for the mounting depth.

How does the Pressure Lock Mounting System secure the speaker, and what mistake should be avoided?

The system clamps directly to drywall without extra hardware; the common error is over-tightening the locks, which can crack the ceiling board.
