Five pairs of white round in-ceiling speakers with paintable magnetic grilles

Earthquake Sound

Earthquake Sound R800 8" In-Ceiling Speakers 5-Pair Pack

SKU CH-TGDK-ACZZE

Five pairs of 8-inch in-ceiling speakers with paintable magnetic grilles, 8-ohm impedance and 92 dB sensitivity

  • TypeIn-Ceiling Speakers
  • 8-ohm impedance matches most amplifiers for easy integration
  • 1-inch silk dome NEO tweeter swivels to direct high frequencies
  • Polypropylene 8-inch woofers with wider surround deliver 45 Hz low-end response
  • 92 dB sensitivity produces loud output from modest power
  • Turn ‘N’ Lock mechanism and spring terminals speed up installation

Whole-home Audio Kit

The pack contains five matched pairs of eight-inch in-ceiling speakers designed for distributed audio systems in residential or light-commercial spaces. Each unit uses a polypropylene woofer and a one-inch silk dome tweeter with a neodymium magnet to cover a frequency range of 45Hz to 20kHz. The eight-ohm impedance suits standard multi-zone amplifiers.

Sustained Output Behaviour

A twelve dB per octave filter network with polyswitch protection manages the crossover between drivers during extended playback. The bumped back basket allows greater cone excursion without mechanical compression when the system runs at higher volumes for long periods. Sensitivity of 92dB at one watt one metre means consistent output levels across multiple rooms without overdriving the amplifier.

Upgrade Path and Limits

The kit replaces older six-and-a-half-inch ceiling models or single-pair stereo sets when broader coverage and deeper bass extension are required. The wider surround and 200W maximum power handling support the jump to larger open-plan areas. Buyers needing smaller cut-out dimensions or a lower profile than the 116mm mounting depth should consider alternative form factors.

Questions about this item

How much power do the R800 speakers draw when running all day at moderate volume?

Each speaker handles up to 200W max with 92dB sensitivity at 1W/1m, so typical listening levels require only a few watts from your amplifier.

What amplifier or receiver do I need to drive these 8-ohm in-ceiling speakers?

Any stereo or multi-channel amplifier stable at 8 ohms with adequate power for your room size will work; the speakers use spring-loaded terminals for standard speaker wire.

Can I mix these R800 units with older 6-ohm or 4-ohm speakers in the same system?

The R800 presents an 8-ohm load, so your amplifier must support mixed impedances per channel; otherwise, use a dedicated zone or impedance-matching volume control.
