Commercial 70 V speaker set

This 11-pair, 22-unit set of Theater Solutions TSQ670 in-ceiling speakers is built for 70 volt distributed-audio systems in commercial and retail spaces. Each unit includes a 6.5 inch poly mica cone woofer and a pivoting silk titanium dome tweeter in a two-way design. The flush-mount housings fit an 8.4375 inch cut-out with a 2.875 inch mounting depth.

Sustained 70 V line performance

The built-in 70 volt transformer offers five tap settings at 16, 8, 4, 2 and 1 watt so each speaker draws only the power needed for its zone. Frequency response runs from 50 Hz to 20 kHz with a sensitivity of 91 dB at 8 ohm, and the 6 dB per octave crossover keeps the drivers balanced during long operating hours. Transformer bypass mode allows the same units to run on a conventional low-impedance amplifier when required.

Pressure Lock installation

Spring-loaded clamps grip the drywall without separate hardware, letting installers secure each speaker in seconds. The low-profile ABS housings and removable grilles can be painted to match the ceiling. Raw wire connections accept stripped cable directly. Professional installation is recommended when the 70 volt transformer taps are used to ensure correct phasing and load calculations.

Questions about this item

How much heat or noise does the 70 V transformer add when the 22 speakers run all day?

The built-in 70 V transformer is passive and adds no fan noise or active heat; each speaker draws only the tapped wattage you select — 16, 8, 4, 2 or 1 watt.

What amplifier or receiver must I already own to drive this 22-unit set?

You need a 70 V line amplifier or receiver with enough total output wattage to cover the combined tap settings you choose across all 22 speakers.

Can I mix these 6.5" in-ceiling speakers with my existing 8-ohm bookshelf speakers on the same amp?

Only if your amplifier offers both 70 V transformer outputs for these speakers and separate 8-ohm outputs for the bookshelf pair; they cannot share the same speaker terminals.
