Eight-Speaker 70 V System

The Theater Solutions TSQ670 set provides eight in-ceiling 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 W down to 1 W, plus a bypass for standard low-impedance use. The package suits installers who need wide, consistent coverage across multiple zones.

70 V Line Practical Limits

The 70 V topology allows long cable runs with minimal signal loss, but total connected load must stay within the amplifier’s rated output. Tap settings of 16, 8, 4, 2 and 1 W let you balance volume per zone, yet the combined wattage of all eight speakers cannot exceed the amp capacity. Professional installation is recommended to verify transformer loading and wiring polarity.

Coverage and Headroom

Frequency response spans 50 Hz to 20 kHz with 91 dB sensitivity at 8 Ω, giving clear voice and background music reproduction in typical ceiling heights. The 6.5 in poly-mica woofers and pivoting silk-titanium tweeters deliver broad dispersion, though deep bass extension is limited by the 50 Hz low-end. The 2.875 in mounting depth fits standard plenum spaces, while the 8.4375 in cutout suits common hole saws.

Questions about this item

Which 70 V tap setting should I use for my install?

The built-in transformer offers five taps at 16, 8, 4, 2 and 1 watt; choose the tap that matches the power you want each speaker to draw from the 70 V line.

What does the 91 dB sensitivity mean when the speakers are driven by a 70 V amplifier?

At 8 ohm impedance the speakers produce 91 dB SPL at 1 metre with 1 watt input, so a 70 V amp set to the same wattage tap will deliver that output level.

How does the 70 V transformer affect wiring distance and speaker count?

The 70 V line lets you run long cable runs and connect multiple speakers in parallel; each speaker’s tap setting determines its share of the amplifier’s total power budget.
