18-Speaker In-Ceiling Set

The Acoustic Audio R191 package supplies eighteen passive in-ceiling speakers for whole-house audio or multi-room home-theatre installations. Each unit uses a two-way design with a 5.25-inch polypropylene woofer and a 12mm soft-dome tweeter. The system is built for flush-mount placement in drywall ceilings or walls.

Pressure Lock Mounting System

Installation relies on a Pressure Lock mechanism that clamps each speaker to the drywall without separate hardware. The required cut-out diameter is 6.61 inches and the mounting depth is 2.8 inches. Ensure the ceiling cavity meets that depth and that no joists or pipes obstruct the opening before cutting.

Amplifier and Wiring Requirements

A home audio receiver or amplifier with raw speaker-wire outputs is needed, delivering between 10 and 200 watts per channel. Use CL3-rated in-wall speaker wire for all runs from the amplifier to each speaker location. Verify your amplifier channel count matches the eighteen-speaker layout you plan.

Questions about this item

How do I verify the 18 speakers are performing correctly after installation?

Play a full-range test signal through your receiver; each of the 18 speakers should reproduce clean output from 45 Hz to 22 kHz at the rated 95 dB sensitivity without distortion.

What does the 18-speaker set include and what must I supply separately?

The set contains 18 in-ceiling speakers with Pressure Lock Mounting System and paintable grilles; you must provide a home audio receiver or amplifier (10–200 W per channel) and CL3-rated raw speaker wire.

Which speaker configuration suits a 9-pair whole-house or home-theatre layout?

The R191 18-speaker pack provides nine stereo pairs, each with a 5.25″ polypropylene woofer and 12 mm soft-dome tweeter, designed for flush-mount installation in a 6.61″ cut-out at 2.8″ depth.
