Six-pair 70 V in-ceiling system

This pack contains three matched pairs of Theater Solutions 3TSQ670 flush-mount speakers built for 70-volt distributed audio. Each unit uses a 6.5-inch poly mica cone woofer and a pivoting silk titanium dome tweeter in a two-way layout. The integrated transformer offers tap settings of 16, 8, 4, 2 and 1 watt, and a bypass mode lets the same hardware run on a conventional amplifier. Frequency response spans 50 Hz to 20 kHz with 91 dB sensitivity at 8 ohm.

Commercial installs needing simple zoning

The 70-volt topology suits retail, restaurant or office ceilings where long cable runs and multiple zones are required. Installers can daisy-chain many speakers from one amplifier without calculating impedance per run. Home users who want a single stereo pair for a living room will find the transformer and multi-tap features unnecessary and should choose a standard low-impedance model instead. Buyers needing weather-rated enclosures for outdoor soffits must look elsewhere.

Spring-lock mounting cuts install time

The pressure-lock clamps grip drywall in a 8.4375-inch cut-out with 2.875-inch mounting depth, requiring no separate hardware. Spring-loaded raw-wire terminals accept stripped conductor directly. Professional installation is recommended when the 70-volt transformer is used, because tap selection and line-level phasing affect system balance. Painting the removable grilles before final snap-in avoids overspray on the drivers.

Questions about this item

What amplifier or receiver do I need to drive these 70 V speakers?

You need a 70 volt amplifier or receiver with enough total wattage for the tap settings you choose across all six speakers.

Can I keep my existing 8 ohm stereo amp and still use these speakers?

Yes, bypass the built-in 70 volt transformer and connect the raw wire terminals directly to an 8 ohm amplifier; the speakers then behave as conventional passive units.

How can I verify the system is performing correctly after installation?

Measure 91 dB output at 1 watt / 1 metre and confirm the frequency response reaches 50 Hz to 20 kHz with a test tone sweep.
