12-pair 70 V in-ceiling speaker set

The Theater Solutions TSQ670 pack contains 24 individual speakers designed for distributed audio in commercial and retail spaces. Each unit includes a built-in 70 V transformer with five tap settings from 16 down to 1 watt. A transformer bypass mode allows the same speakers to serve standard low-impedance systems. The two-way design uses a 6.5-inch poly mica cone woofer and a pivoting silk titanium dome tweeter.

Pressure Lock mounting cuts install time

Spring-loaded clamps grip drywall without separate hardware, letting a single installer seat each speaker in seconds. The round cut-out must measure 8.4375 inches and the cavity needs at least 2.875 inches of depth. Professional installation is recommended when the 70 V transformer taps are used, because incorrect tap selection or wiring polarity can unbalance the line and overload the amplifier.

50 Hz – 20 kHz coverage at 91 dB sensitivity

The 6 dB per octave crossover blends the woofer and tweeter for full-range reproduction in background-music and paging roles. At the 16 watt tap each speaker draws modest line current, so a single 70 V amplifier can drive all 24 units with headroom to spare. At the 1 watt tap the same amplifier can cover larger zones, but maximum SPL drops accordingly and the system may struggle in high-noise areas.

Questions about this item

How can I verify the TSQ670 speakers are performing correctly after installation?

Measure output with a 70 volt amplifier; each speaker should reach 91dB sensitivity and cover a frequency response of 50Hz to 20kHz from the 6.5" poly mica woofer and pivoting silk titanium tweeter.

What does the 12-pair pack contain and what extra items are required?

The box includes 24 in-ceiling speakers with built-in 70 volt transformers, removable grilles, and spring-loaded pressure-lock clamps; you must supply a 70 volt receiver or amplifier and speaker wire separately.

Which tap setting should I choose on the 70 volt transformer for my zone?

Select the 16, 8, 4, 2, or 1 watt tap that matches the power budget of each speaker run; lower taps reduce load on the amplifier while maintaining coverage across the 50Hz to 20kHz range.
