Five-Speaker In-Ceiling Set

The Acoustic Audio R191 is a five-piece flush-mount speaker system designed for home-theatre surround sound. Each unit uses a 5.25-inch polypropylene woofer paired with a 12mm soft-dome tweeter in a two-way configuration. The set covers front, centre and rear channels for immersive audio. Paintable grilles and ABS housings blend with any ceiling finish.

Upgrade From Basic TV Audio

This system replaces built-in television speakers or simple soundbars that cannot deliver true channel separation. The jump is worthwhile when a receiver or amplifier with raw speaker-wire outputs is already available or planned. Passive design means no separate power outlets are needed at each speaker location. Installation uses a pressure-lock mechanism that clamps to drywall without extra hardware.

Room-Filling Coverage With Defined Limits

Frequency response spans 45 Hz to 22 kHz at 95 dB sensitivity and 8-ohm impedance, giving clear dialogue and detailed effects in medium-sized rooms. Amplifier power between 10 and 200 watts per channel is supported for clean headroom. The speakers fit a 6.61-inch cut-out with 2.8-inch mounting depth. They cannot produce sub-bass impact below 45 Hz or serve large auditorium spaces.

Questions about this item

What size ceiling cut-out and mounting depth does each speaker require?

Each speaker fits a 6.61" round hole and needs 2.8" of mounting depth behind the ceiling.

How does the Pressure Lock Mounting System secure the speaker, and what common step is missed?

The system clamps the speaker to drywall without hardware; the step often missed is tightening the clamps evenly so the grill sits flush.

What speaker wire rating and amplifier power range are needed for safe, long-term use?

Use CL3-rated in-wall speaker wire and an amplifier delivering 10 to 200 watts per channel at 8 ohms.
