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

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.
