  • 3-way design with woofer, midrange and tweeter delivers full-range sound coverage

6.5-Inch In-Ceiling 3-Way Speaker Pair

These passive speakers mount flush in a ceiling and cover a frequency range of 45Hz to 20kHz with a sensitivity of 93dB at 8 ohms. Each unit uses a 6.5-inch poly cone woofer, a poly mica midrange and a 13mm soft dome tweeter linked by a 3-way crossover. They are built for stereo or surround systems driven by a standard home audio receiver.

Upgrade From Built-In TV Audio

The 3-way design separates bass, midrange and treble more cleanly than typical TV speakers or basic 2-way in-ceiling models. The wider dispersion pattern fills a room more evenly, making the jump worthwhile when dialogue clarity and music detail matter more than a soundbar can deliver. They require an external amplifier capable of 10 to 300 watts per channel.

Tool-Free Pressure Lock Mounting

The Pressure Lock system clamps the 9.17-inch frame to drywall through a 7.87-inch cutout with no separate hardware needed. A mounting depth of 3.43 inches must be clear above the ceiling. Spring-loaded terminals accept raw speaker wire; the most common issue is stripping too little insulation so the wire slips out when the lever releases.

Questions about this item

What ceiling hole diameter and mounting depth does the 6.5-inch speaker require?

Cut a 7.87-inch round hole and ensure at least 3.43 inches of clearance above the ceiling for the speaker housing.

How do the Pressure Lock Mounting clamps secure the speaker without screws?

After inserting the unit, tighten the built-in clamps by hand until they press firmly against the drywall; skipping this step leaves the speaker loose.

When should the butyl rubber surrounds on the woofers be inspected or replaced?

Check the surrounds every few years; if they become brittle or cracked, replace the affected driver to maintain the 45Hz low-frequency response.
