Eight-Speaker In-Wall System

The Acoustic Audio HD-650 pack supplies eight flush-mount speakers for whole-house audio or surround-sound layouts. Each unit uses a traditional passive design that draws power from your existing receiver or amplifier.

Compatibility Check

Verify your amplifier delivers between 10 and 300 watts per channel into an 8-ohm load. You will also need CL3-rated in-wall speaker wire and a rectangular cut-out measuring 7.28" by 10.71" with at least 2.8" of mounting depth behind the wall.

Build Integration

The Pressure Lock Mounting System clamps each speaker to drywall without separate hardware, while spring-loaded terminals accept raw wire for quick connection. Paintable ABS housings and removable grilles blend into the décor, freeing floor space otherwise occupied by box speakers.

Questions about this item

What comes in the box and what extra items are needed to install the HD-650 speakers?

The box contains eight in-wall speakers with removable grilles and the Pressure Lock Mounting System that clamps to drywall without extra hardware. You must supply a home audio receiver or amplifier with raw speaker wire outputs, plus CL3-rated in-wall speaker wire to connect them.

How do I decide between the available versions or capacities of the HD-650 set?

This product is sold only as an eight-speaker pack with 6.5-inch woven fiber woofers and pivoting titanium tweeters; there are no alternative driver sizes or pack quantities listed, so the single configuration shown is the only option.

What does the 98 dB sensitivity rating mean when the speakers are powered in a real system?

At 8 ohms the speakers produce 98 dB output with one watt of input, so a receiver delivering between 10 and 300 watts per channel will drive them to loud, clean levels without needing excessive power.
