Earthquake Sound

Earthquake Sound R800 8" In-Ceiling Speakers 4-Pairs

SKU CH-73D4-HSVWN

Eight-inch in-ceiling speakers with polypropylene woofers, silk-dome tweeters and paintable magnetic grilles, sold as four stereo pairs

  • TypeIn-Ceiling Speakers
  • 8-ohm impedance suits most home amplifiers
  • 92 dB sensitivity delivers strong output from modest power
  • 200 W peak handling supports dynamic movie and music peaks
  • 45 Hz low-frequency reach adds weight without a subwoofer
  • Turn ‘N’ Lock mechanism cuts installation time in the ceiling

Eight-Inch In-Ceiling Speaker Set

This set contains four pairs of Earthquake Sound R800 in-ceiling speakers, giving eight individual drivers for multi-room audio or a full surround installation. The 8-ohm impedance matches most home amplifiers and receivers without specialised loading. Installers can cover a whole floor or a large open-plan area from a single pack. Homeowners wanting discrete background music or cinema sound will find the quantity convenient.

Magnetic Paintable Grille and Spring Terminals

Each unit uses a 10-5/8-inch grille that attaches magnetically and accepts paint for a seamless ceiling blend. The edgeless design removes visible bezels once mounted. Custom spring-loaded terminals accept bare wire quickly, while the Turn ‘N’ Lock mechanism secures the speaker to the ceiling without separate brackets. A 9-1/2-inch cut-out and 4-9/16-inch mounting depth fit standard joist bays.

Upgrade From Smaller Drivers or Fewer Zones

Builders replacing 6.5-inch models gain the 8-inch polypropylene woofer and 1-inch silk dome tweeter for extended low-frequency response down to 45Hz. The 200W maximum power handling and 92dB sensitivity suit larger rooms where smaller speakers run out of headroom. The 12dB crossover with thermal protection keeps the tweeter safe at high volumes. Buyers needing more than eight channels or weather-rated outdoor units should look elsewhere.

Questions about this item

What impedance does the 8-ohm rating present to an amplifier, and what power level does it handle?

The speakers present a single 8-ohm load and are rated for 200 W maximum power handling, so they work with typical home receivers rated for 8-ohm loads.

What ceiling cut-out and mounting depth are required for the 10-1/2" frame?

Cut a 9-1/2" (240 mm) diameter hole and allow at least 4-9/16" (116 mm) of clearance above the ceiling for the speaker basket and magnet.

How does the Turn 'N' Lock mechanism secure the speaker, and what step is often missed?

Insert the speaker into the cut-out, then rotate the locking ring until the spring-loaded clips engage the ceiling material; the step often missed is turning far enough to hear each clip click into place.
