Earthquake Sound R650 In-Ceiling Speakers

The Earthquake Sound R650 is a set of four 6.5-inch in-ceiling speakers designed for distributed home audio or surround sound systems. Each unit handles 300W of power with an 8-ohm impedance and delivers a frequency response of 40Hz-21kHz at 93 dB sensitivity. The 1-inch silk dome NEO tweeter swivels for directional high-frequency aiming.

Check Ceiling Cut-Out And Amplifier Match

Verify your ceiling can accommodate a 7-7/8-inch (200mm) cut-out diameter and at least 4-inch (101mm) of mounting depth behind the surface. Ensure your amplifier or receiver is stable driving an 8-ohm load across four speakers simultaneously. The spring-loaded terminals accept bare wire for quick connection.

Magnetic Grille And Turn-N-Lock Mounting

The paintable rust-resistant grille attaches magnetically for a clean, edgeless look that blends into the ceiling. A Turn ‘N’ Lock mechanism secures the speaker to the drywall without separate brackets. The bumped back basket and wider surround allow high excursion for deeper bass, while a 12 dB/Octave crossover and thermal tweeter protection maintain driver integrity.

Questions about this item

What comes in the box and do I need to buy mounting hardware separately?

The package includes two pairs of R650 in-ceiling speakers with magnetic grilles and swivel tweeters; the Turn ‘N’ Lock mechanism secures them to the ceiling so no extra mounting brackets are required.

Should I choose the 6.5" model or a different size for my room?

The R650 is only offered in this 6.5" two-pair configuration, delivering a 40 Hz – 21 kHz response and 93 dB sensitivity suited to medium-sized living areas.

What does the 300 W rating mean when the speakers are installed in my ceiling?

The 300 W figure is the peak power handling; with 8-ohm impedance and 93 dB sensitivity the pair will play loudly on a modest amplifier while the 12 dB/octave crossover and thermal tweeter protection keep distortion low at high volumes.
