Five-Speaker In-Ceiling Set

The Acoustic Audio HD-5 provides a five-piece flush-mount array for home-theatre surround sound. Two-way drivers handle centre, front and rear channels in a single package. Passive design draws power from any compatible receiver or amplifier. Integrated Pressure Lock clamps secure each unit to drywall without separate hardware.

Thermal Noise Power

Passive construction means no built-in amplification, fan noise or heat generation from the speakers themselves. System draws only the wattage supplied by the external receiver, rated between 10 and 250 watts per channel. Sensitivity reaches 97dB at 8 ohms for efficient output. Low-profile ABS housings sit 2.8 inches deep in the ceiling cavity.

Sustained Load Behaviour

Woven-fiber 5.25-inch woofers with butyl rubber surrounds maintain cone control during extended playback. Pivoting titanium tweeters preserve high-frequency dispersion across long listening sessions. Frequency response spans 40Hz to 22kHz without active thermal limiting. Paintable grilles and durable housings resist environmental stress over time.

Questions about this item

How do I install the HD-5 speakers and what step is often missed?

Cut a 6.61" round hole, push the speaker up until the Pressure Lock Mounting System clamps tight to the drywall, and ensure the 2.8" mounting depth clears any joists or insulation before locking.

What maintenance or replacement will the HD-5 set need later?

The removable grilles can be painted to match décor changes; the butyl rubber surrounds and titanium tweeters are built for long life, so no scheduled driver replacement is expected under normal use.

What limit appears first during sustained high-volume playback?

The receiver or amplifier must stay between 10 and 250 watts per channel; exceeding 250 watts risks thermal compression or driver damage before the 97dB sensitivity ceiling is reached.
