  • TypeIn-Ceiling Speakers
  • Wide sound dispersion integrates with any audio system

Seven-Speaker In-Ceiling Set

This seven-piece home-theater system places flush-mount speakers overhead for a front, centre and surround layout. The passive design draws power from any receiver or amplifier with raw speaker-wire outputs. It is intended for buyers who want discreet, whole-room audio without floor-standing cabinets.

Flush Mount With Pressure Lock

Each unit clamps to drywall through a 9.45" cut-out using a tool-free Pressure Lock mechanism that requires no separate hardware. The 3.78" mounting depth fits standard joist bays, and the 10.83" overall diameter covers the opening cleanly. Spring-loaded terminals accept bare wire, while paintable ABS housings and removable grilles blend with any ceiling finish.

Passive 3-Way Frequency Limits

The 8" poly-cone woofers, poly-mica midranges and 13mm soft-dome tweeters are crossed over at factory-set points for a stated 40Hz–20 kHz response at 95 dB sensitivity. Amplifier power must stay between 10 and 350 watts per channel; lower power risks insufficient headroom, while higher power can damage the passive crossovers. Buyers needing active DSP, wireless streaming or sub-40 Hz extension will need additional equipment.

  • Traditional passive design powered by your receiver or amp

Questions about this item

What frequency range does the 8-inch woofer cover and at what sensitivity?

The system reproduces 40 Hz to 20 kHz at 95 dB sensitivity measured at 8 ohms.

What ceiling cut-out and depth are required for the flush-mount housings?

Each speaker needs a 9.45-inch round hole and 3.78 inches of mounting depth behind the ceiling.

How do the Pressure Lock clamps secure the speakers without hardware?

The spring-loaded arms expand behind the drywall when you tighten the front screws; the mistake is not tightening them enough to engage the clamps fully.
