Seven-speaker home-theatre set

The Goldwood Sound HD-650 delivers a complete 7-channel surround system using flush-mount in-wall speakers. A dedicated centre channel plus matched front, side and rear units create an immersive soundstage for films and music. Traditional passive design means any compatible receiver or amplifier can drive the system without proprietary electronics. Installation suits both new-build and retrofit projects.

Thermal noise and power handling

Passive operation produces no fan noise or active heat, keeping the listening room silent when the system is idle. Each speaker handles 10 to 300 watts per channel, so a wide range of amplifiers can be used without risk of overload. Sensitivity of 98 dB at 8 ohms ensures strong output levels even with modest amplifier power. Frequency response extends from 30 Hz to 22 kHz for full-range reproduction.

Build integration and wiring

The Pressure Lock mounting system clamps each unit to drywall without separate hardware, fitting a cut-out of 7.28" x 10.71" and a mounting depth of 2.8". Overall dimensions of 8.54" x 12.01" leave a low-profile finished appearance. Spring-loaded raw-wire terminals accept CL3-rated in-wall speaker cable for code-compliant runs. Removable ABS grilles can be painted to match any décor.

Questions about this item

How do I install the HD-650 speakers using the Pressure Lock Mounting System, and what step do people often get wrong?

Cut a 7.28" x 10.71" rectangular hole, insert the speaker, and tighten the clamps until they lock against the drywall; the step often missed is ensuring the clamps fully engage behind the wall for a secure flush mount.

What maintenance or replacement will the HD-650 speaker set need over time?

The 6.5" woven fiber woofers with butyl rubber surrounds and pivoting titanium tweeters are designed for long life; the removable grilles can be removed for dusting or painted to match décor if desired.

What is the first limit reached when driving the HD-650 set at high volume for extended periods?

The amplifier must supply between 10 and 300 watts per channel; exceeding 300 watts risks damage, while the 98dB sensitivity at 8 ohms means loud levels are reached with moderate power.
