Tannoy PS 110 Subwoofer — Made in Canada, 10-Inch, 110W MOSFET

Tannoy PS 110 Active Sub-Woofer — Made in Canada, 10-Inch Long-Throw Driver, 110-Watt MOSFET Amplifier, Speaker Level and Line Level Connections

A Canadian-built 10-inch powered subwoofer in good condition, with a rear panel that will connect to almost anything, vintage or modern.

Made in Canada

Start with where it was made, because it is not what anyone expects from a Tannoy. This one was built in Canada — the plate on the back says so, and carries CSA certification alongside it. For a British marque best known for Scottish-built studio monitors, a Canadian-made subwoofer is an unusual thing to find.

Driver and Amplifier

The PS 110 pairs a long-throw 10-inch woofer in a front-ported cabinet with a 110-watt MOSFET amplifier built into the rear panel. Front porting matters on a subwoofer more than on anything else in a system: it means the cabinet can go against a wall or into a corner without the port loading against the room and turning the bass into one loud note.

The Connection Panel

The connection panel is the reason this one is worth hunting for. There are line level RCA inputs and outputs for left and right, and separate speaker level binding posts for left and right — and crucially, a second pair of binding posts marked High Pass Out.

Works With Vintage Systems

That is what makes this subwoofer work with a vintage amplifier or receiver that has no subwoofer output at all. Run speaker cable from the amplifier into the Speaker Level In posts, then a second pair from the High Pass Out posts to your main speakers, and the job is done. Better still, the main speakers come out of it high-passed rather than simply passed along, so they are relieved of the deep bass they were struggling with — which is where most of the audible improvement in adding a subwoofer actually comes from. Most subwoofers built in the last twenty years assume a modern receiver with a dedicated LFE jack and cannot be used any other way. This one does not care what decade your amplifier came from.

Modern System Connection

For a modern system, the line level inputs take the subwoofer output from a receiver or processor, and the line level outputs pass the signal onward.

Room Adjustment

The adjustment set is just as thorough. The crossover sweeps from 40 to 150 Hz. There is a sub level pot for balancing the subwoofer against the mains, an LF tilt control for shaping the bottom end to suit the room, and a phase switch offering 0 or 180 degrees. Most subwoofers give you a level knob, a crossover dial and nothing else. This gives you enough adjustment to actually solve a room rather than compromise with it, which is the whole difficulty with siting a subwoofer in a normal-sized listening room. The power switch has three positions — Auto, On and Off — so it can sleep with the system or stay awake as you prefer.

What It Does and Does Not Do

On what it does and does not do: this is a controlled, well-behaved subwoofer rather than a brute. It reaches down into the high 20s with real pitch definition — you hear which note the bass player is on, not just that something low happened. It suits bookshelf speakers and modest towers rather than high-output monitors, and an onboard limiter protects the driver from overexcursion if it is asked for more than it has. Maximum output is 110 dB.

Cabinet and Condition

The cabinet is finished in black vinyl and sits on four substantial rubber feet that keep it from coupling into the floor.

Tested Here

It has been tested here to confirm it performs as originally designed, and grades good.

A Canadian-built 10-inch subwoofer that connects to a 1975 receiver as happily as to a modern processor, and can be dialled into a real room rather than placed and hoped for.
