Ten-Speaker In-Wall Set

The Goldwood Sound HD-650 package delivers ten 6.5-inch in-wall speakers for whole-house audio or surround-sound installations. Each unit uses a two-way design with a woven-fiber woofer and a pivoting titanium tweeter. The flush-mount housings fit a rectangular cutout of 7.28 by 10.71 inches and require a mounting depth of 2.8 inches. Removable grilles can be painted to match any décor.

Passive Design and Mounting

These passive speakers draw power from an existing home audio receiver or amplifier with raw speaker-wire outputs. The Pressure Lock Mounting System clamps the ABS housings to drywall without separate hardware. Spring-loaded terminals accept bare wire, and CL3-rated in-wall speaker cable completes the connection. The system requires an amplifier capable of 10 to 300 watts per channel.

Frequency Range and Power Handling

Frequency response spans 30 Hz to 22 kHz at 98 dB sensitivity and 8-ohm impedance, covering full-range sound for music and movie soundtracks. The 100-watt continuous and 300-watt peak ratings provide headroom for dynamic peaks in larger rooms. Buyers needing powered speakers or wireless connectivity will need a different solution.

Questions about this item

At what volume level does the 98dB sensitivity and 300-watt power limit become a constraint during extended listening?

The speakers handle up to 300 watts per channel with 98dB sensitivity at 8 ohms, so sustained output stays clean until the amplifier reaches that ceiling.

How much heat do the ABS housings and butyl-rubber surrounds dissipate when driven continuously at high levels?

Passive components generate negligible heat; the ABS enclosures and butyl-rubber surrounds remain cool during all-day operation.

Which amplifier specifications must my receiver meet to drive this 10-speaker set properly?

Any home audio receiver or amplifier with raw speaker wire outputs rated between 10 and 300 watts per channel at 8 ohms will work.
