Center Channel for Home Theater

The Acoustic Audio HD-6c is a flush-mount center channel speaker designed for home theater surround sound or whole-house audio systems. Its traditional passive design connects directly to any home audio receiver or amplifier using raw speaker wire outputs. The speaker integrates with new and existing setups without requiring proprietary electronics. Buyers who need an active soundbar with built-in streaming or HDMI connectivity will not find those features here.

Fits Standard Wall Cavities

The rectangular cutout measures 19.21" x 7.4" with a 3.03" mounting depth, while the overall grille dimensions are 20.47" x 8.66". A Pressure Lock Mounting System clamps the ABS housing to drywall without separate hardware, and spring-loaded terminals accept bare wire. The removable white grill can be painted to match the surrounding décor. Installers without access to CL3-rated in-wall speaker wire must source it separately to meet code requirements.

High Sensitivity 8-Ohm Load

Dual 6.5" woven fiber woofers with butyl rubber surrounds and a 12mm soft dome tweeter deliver a frequency response of 33 Hz to 22 kHz at 98 dB sensitivity. The 8-ohm nominal impedance presents an easy load for amplifiers rated between 10 and 350 watts per channel, with 175 watts RMS and 350 watts peak power handling. The passive crossover and sealed enclosure produce no fan noise or active heat, leaving thermal management entirely to the driving amplifier.

Questions about this item

What is the lowest frequency the Acoustic Audio HD-6c can reproduce before output drops off?

The speaker reaches down to 33 Hz, giving solid low-end presence for dialogue and effects in a center-channel role.

How much heat or noise does the HD-6c generate during a full-day movie marathon?

As a passive design it produces no fan noise or active heat; only the amplifier warms up, and the 98 dB sensitivity keeps amp current modest even at high volumes.

Which amplifier specs must I already have to drive this in-wall center speaker safely?

You need a home audio receiver or amplifier with raw speaker-wire outputs rated between 10 and 350 watts per channel into 8 ohms, plus CL3-rated in-wall speaker cable for the run.
