Eight-speaker flush-mount set

The Acoustic Audio R191 package supplies eight passive in-ceiling speakers for whole-house audio or home-theatre surround installations. Each unit uses a two-way design with a 5.25" polypropylene woofer and a 12mm soft-dome tweeter. They connect to any receiver or amplifier through raw speaker wire terminals. The system is built for distributed sound rather than critical near-field listening.

95 dB sensitivity and 45 Hz–22 kHz range

With a rated sensitivity of 95 dB at 8 ohms the speakers play loudly on modest amplifier power between 10 and 200 watts per channel. The passive crossover keeps the load stable across the 45 Hz to 22 kHz frequency span. No active electronics or fan noise are present, so thermal output in the ceiling cavity is negligible. CL3-rated in-wall cable is recommended for the speaker runs.

Pressure-lock mounting and paintable grilles

The Pressure Lock Mounting System clamps each 7.48" frame to drywall through a 6.61" cut-out with a 2.8" mounting depth, requiring no separate hardware. Durable ABS housings and removable grilles can be painted to match the ceiling. Raw wire clamp or solder terminals accept standard speaker cable. Buyers who need powered speakers, wireless streaming or weather-rated outdoor models should look elsewhere.

Questions about this item

How do the Pressure Lock Mounting System clamps secure the speakers in a 6.61-inch hole?

The clamps tighten against the drywall from inside the cut-out, holding the 7.48-inch frame flush without screws or separate brackets.

What part of the 2-way driver array is most likely to need attention after years of use?

The butyl rubber surrounds on the 5.25-inch woofers can dry out and lose compliance, while the 12mm soft-dome tweeters typically remain stable.

At what amplifier power does the 8-ohm load start to compress dynamically during long sessions?

Continuous output above roughly 200 watts per channel into 8 ohms will push the 95 dB sensitivity limit and trigger thermal compression.
