Five-Pair In-Ceiling Set

The Acoustic Audio R191 pack supplies ten passive speakers for whole-house audio or home-theatre surround installations. Each unit uses a two-way design with a 5.25-inch polypropylene woofer and a 12mm soft-dome tweeter. The Pressure Lock mounting system clamps to drywall without separate hardware. Grilles can be painted to match the ceiling.

Sustained Output Behaviour

Rated at 95dB sensitivity and 8-ohm impedance, the speakers maintain consistent output during extended listening sessions when driven within the 10-to-200-watt-per-channel window. The butyl rubber surrounds resist fatigue, and the ABS housings dissipate heat without colouration. Frequency response spans 45Hz to 22kHz across the operating range.

Pre-Installation Checks

Verify that your receiver or amplifier provides raw speaker-wire outputs and can deliver between 10 and 200 watts per channel into 8 ohms. Confirm the ceiling cavity allows a 2.8-inch mounting depth and a 6.61-inch cut-out diameter. Use CL3-rated in-wall speaker wire for the runs from the amplifier to each location.

Questions about this item

Do the R191 speakers produce noticeable heat or fan noise during all-day use?

The passive R191 design has no amplifier or fan inside, so it generates no heat and makes no noise of its own; only the connected receiver or amplifier will warm up.

What must I already own to power these five speaker pairs?

You need a home audio receiver or amplifier with raw speaker-wire outputs that delivers between 10 and 200 watts per channel into 8 ohms, plus CL3-rated in-wall speaker wire for the runs.

Will the R191s blend with my older 8-ohm bookshelf speakers in the same system?

Yes, the R191s are rated at 8 ohms and 95 dB sensitivity, matching typical legacy bookshelf models so they can share the same receiver channels without level mismatch.
