In-ceiling 5-speaker set for whole-room audio

This five-piece in-ceiling system uses a frameless, flush-mount design that blends into the ceiling. Each unit is a passive 3-way speaker with a 6.5-inch poly cone woofer, a Mylar midrange and a 0.5-inch Mylar tweeter. The Pressure Lock mounting system clamps to drywall without separate hardware. The set suits owners who want discreet, room-filling sound driven by an existing receiver or amplifier.

Best for multi-room or home-theatre installs

Buyers who already own a home audio receiver or amplifier with raw speaker wire outputs can simply connect and play. The speakers require 10 to 250 watts per channel and CL3-rated speaker wire, so a compatible amp and wiring are essential. Shoppers without a separate amplifier, or who need powered speakers with built-in streaming, should look at a different product type.

45 Hz to 20 kHz frequency response at 92 dB

The published frequency range of 45 Hz to 20 kHz and 92 dB sensitivity at 8 ohms determine how low and how loud the system plays in your room. If your content demands deeper bass extension or higher output than these figures provide, this set will not meet that requirement.

Questions about this item

How do I install the CSic64 speakers and what step do people often miss?

Cut an 8.27" hole, push the speaker up until the Pressure Lock Mounting System clamps to the drywall — no hardware needed — then attach the magnetic frameless grill. The step often missed is verifying the 2.99" mounting depth clearance before cutting.

What maintenance or replacement will these in-ceiling speakers need over time?

The 6.5" poly woofers with butyl rubber surrounds and .5" mylar tweeters are passive with no user-serviceable parts. Under normal use the magnetic grills may need occasional dusting; the drivers themselves require no scheduled maintenance.

What is the first limit I will hit when running these speakers at high volume for long periods?

The 250-watt-per-channel maximum power handling and 92dB sensitivity at 8 ohms set the thermal limit. Exceeding 250 watts or driving sustained peaks beyond the 45Hz-20kHz range risks overheating the 3-way passive crossovers.
