Flush-Mount In-Wall Speaker Set

This Goldwood Sound HD-650 pack contains sixteen passive speakers designed for flush installation in walls or ceilings. Each unit uses a 6.5" woven-fibre woofer and a pivoting titanium tweeter in a two-way layout. The set suits whole-house audio or home-theatre surround installations.

Check Amplifier Power And Wiring

Verify that your receiver or amplifier delivers between 10 and 300 watts per channel into 8 ohms. You must run CL3-rated in-wall speaker wire from the amp to each location. The spring-loaded terminals accept raw wire only, so no banana plugs or spade connectors are needed.

Pressure-Lock Mounting And Cut-Out Size

The Pressure Lock system clamps each speaker to drywall without separate hardware, requiring a rectangular cut-out of 7.28" x 10.71" and 2.8" mounting depth. The low-profile ABS housings and paintable grilles sit almost flush, leaving floor space free for furniture or additional equipment.

Questions about this item

Does the 16-pack include speaker wire or do I need to buy CL3 rated wire separately?

The package contains sixteen in-wall speakers with removable grilles and the Pressure Lock Mounting System; CL3 rated raw speaker wire must be purchased separately to connect them to your receiver.

Should I choose a different model if my amplifier delivers more than 300 watts per channel?

The HD-650 is rated for amplifiers between 10 and 300 watts per channel at 8 ohms; exceeding 300 watts risks damage, so a higher-power speaker would be required for stronger amps.

What does the 98 dB sensitivity figure mean for everyday listening volume?

At 98 dB sensitivity the speakers produce loud, clear output with modest amplifier power, so typical home theater levels are reached well before the 300 watt limit.
