PSI Audio Sub A225-M (metal black)

The A225-1 sub-woofer/bass extension is equally suited to use as a
mono sub-woofer in a surround sound application or as a bass extension in a stereo system. Designed to work in
harmony with the A225-1 Sub, all PSI Audio 'A' series speakers feature a frequency response roll-off function that,
when combined with the A225-1 Sub, extends the frequency range down to an incredible 24 Hz, whilst maintaining
a flat response.
The powerful class G outputs feature PSI Audio's unique "AOI" output stages, giving the A225-1 an
unprecedented impulse behavior. Each driver and amplifier unit is secured by a protection circuit, which is
monitored by a red LED on the front panel.
The electronics are housed in a unit mechanically isolated from the speaker cabinet to avoid resonance at high
sound pressure levels. To provide stability and avoid cabinet resonance A225-1 is built with a double-box design,
combining two cabinets into a single beautifully finished unit.
