Feature-Loaded Tannoy 10″ Active Subwoofer PS 110

The PS 110 from Tannoy is an integrated powered subwoofer designed to work either as an adjunct to a stereo playback system or to provide LFE (the Low Frequency Effects sub channel) in a surround system.

The PS 110 combines a long-throw, 10-inch woofer in a front-ported enclosure, with a 110-watt MOSFET amplifier and crossover built into the back of the cabinet. The case is finished in black vinyl, and four hefty rubber feet help prevent the box from coupling with the floor.

The rear panel offers high and low level inputs with pass through for the former to connect to main (front) speakers crossed over at 80hz, and pass through for the latter to connect an additional subwoofer if desired.

The crossover point is adjustable from 40 to 150 Hz, or it can be bypassed entirely, thereby feeding a full-range signal to both monitors and subwoofer.

Other controls include a subwoofer level pot for setting the overall subwoofer/monitor balance, an LF boost knob that raises the extreme low 31 to 63Hz band by an overall +4dB linear shelf, and switches for ground lift and phase reverse. The power supply is internal (with removable AC cord), and it supports an optional auto-power mode.

Between the phase reverse, all-pass/lowpass modes, crossover frequency, LF boost and sub level pots, the PS 110 can be tweaked out to work in most any acoustical space. Although LF energy is generally nondirectional, finding the exact spot to locate any sub in a small listening room can be tricky, and the degree of flexibility offered by the PS 110’s controls really helps the fine-tuning process.

The system is capable of maximum SPLs of 110 dB, but to prevent over-excursion or damage from pushing the woofer too hard, an onboard limiter kicks in. The limiter is inaudible, except in extreme conditions.
