Theater Solutions TSQ670-5S 5-Pack

The Theater Solutions TSQ670-5S is a five-pack of 6.5-inch in-ceiling speakers designed for distributed audio systems. They suit commercial venues, retail spaces and whole-home installations where multiple zones share a single amplifier. The 70-volt topology allows long cable runs without heavy gauge wire.

70-Volt Transformer Tap Limits

Each speaker includes a built-in transformer with five tap settings at 16, 8, 4, 2 and 1 watt. The total tapped wattage across all connected speakers must not exceed the amplifier rated output, otherwise the amplifier will clip or shut down. In bypass mode the speakers present an 8-ohm load and require a compatible low-impedance amplifier. The 70-volt line is not compatible with standard home-theatre receivers lacking transformer outputs.

Quick-Install Mounting Constraints

The pressure-lock clamps secure the 9.3125-inch baffle to drywall through an 8.4375-inch cut-out with a 2.875-inch mounting depth. No separate hardware is needed, but the ceiling cavity must accommodate the depth and the spring-loaded wire terminals accept only bare conductor. Professional installation is recommended for 70-volt wiring to observe polarity and tap selection across all five units.

Questions about this item

Which tap setting should I choose for background music in a retail space?

The built-in transformer offers 16, 8, 4, 2 and 1 watt taps; lower taps such as 2 W or 4 W are typical for background levels, while 8 W or 16 W suit louder paging or music zones.

What does the 91 dB sensitivity mean for my 70 V amplifier?

At 91 dB sensitivity, each speaker delivers strong output from modest amplifier power; a 70 V amp driving the 4 W tap will give clear, room-filling sound without needing high-wattage channels.

How does the 70 V transformer affect wiring compared to standard 8 ohm speakers?

The 70 V transformer lets you run many speakers on a single cable run with minimal loss; you simply set each speaker to its required wattage tap and parallel them on the same line.
