Four-Speaker In-Ceiling Bundle

This package contains four KLH M-8602-C in-ceiling speakers built for indoor or outdoor use. Each unit uses a sealed and tuned steel enclosure with a 6.5" Kevlar/fiberglass woofer and a 1" silk dome tweeter. The set suits homeowners adding distributed audio to multiple rooms without visible cabinets.

Straightforward Mounting With Four Tabs

Every speaker includes four mounting tabs and requires a cutout diameter of 8.9 inches with a mounting depth of 8.75 inches. The 7.2 lb weight means ceiling joists must carry the load securely. The main difficulty is cutting accurate holes and running speaker cable through finished ceilings before fixing the tabs.

Steady Output At Rated Power

Frequency response spans 50 Hz to 20 kHz with sensitivity of 89 dB and a recommended power range of 50 W to 175 W. The sealed steel box controls cone motion during extended playback so thermal compression stays low. Drivers maintain composure through long listening sessions rather than only brief peaks.

  • 1" silk dome tweeter extends clear detail to 20 kHz

Questions about this item

How can I confirm the speakers are performing within the 50 Hz to 20 kHz range after installation?

Play a frequency sweep test tone and listen for smooth output from low bass through high treble without audible gaps or distortion.

What comes in the 4-pack and what extra items are needed to mount them?

The box contains four M-8602-C speakers with integrated mounting tabs; you will need speaker wire, an amplifier, and standard ceiling-cutting tools.

Which version of the M-8602-C should I choose for a room needing 89 dB sensitivity and 50–175 W power handling?

This single Maxwell Series version already provides 89 dB sensitivity and a 50–175 W recommended power range, so no alternate model is required.
