PSI A 225-M Active Studio Sub, Red - PSI-A225M

PSI A 225-M Active Studio Sub, Red - PSI-A225M

The Red PSI A225-M is an active subwoofer suited as either a mono sub within a surround system, or as a bass-extension in a stereo setup. All PSI Audio A-Series speakers feature a frequency response roll-off function that, when combined with the A225-M 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-M 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. Two cabinets are combined into a single unit to increase stability and avoid cabinet resonance.
