Powered Subwoofer with Integrated Amplifier

The Acoustic Audio PSW12 is a self-powered 12-inch subwoofer built for home-theatre and surround-sound systems. Its integrated high-efficiency amplifier delivers 500 watts peak power so the unit drives itself without an external amp. Standard dual RCA inputs connect directly to a receiver’s dedicated sub-out, while high-level raw-wire terminals allow use with stereo amplifiers that lack a pre-out. Automatic signal sensing switches the sub on and off with the system.

24 Hz Low-Frequency Extension

The cabinet is tuned to reproduce frequencies down to 24 Hz, reaching the deepest fundamentals in movie soundtracks and music. A long-throw 12-inch woofer with a high-rigidity PVA-treated cone moves the air volume needed for that extension. The 40 to 140 Hz crossover knob and 0 to 180 degree phase switch let you align the subwoofer’s output with the main speakers so the transition stays smooth at the chosen crossover point.

Sustained Output with Bass-Reflex Loading

A bottom slotted port and bass-reflex cabinet design reduce port compression during extended low-frequency passages. Internal bracing and vibration-absorbing feet keep the MDF enclosure stable when the amplifier drives the woofer continuously at high levels. The auto on/off circuit prevents the amplifier from idling between sessions, so thermal load stays controlled during long movies or listening sessions.

Questions about this item

How loud can the 500 watt peak amplifier actually play in my room?

The built-in amplifier delivers 500 watts peak power and the driver reaches 98 dB sensitivity at 8 ohms, so typical living-room listening levels are well within its capability.

What does the 40 to 140 Hz crossover knob control on this subwoofer?

It sets the upper frequency limit where the subwoofer hands off to your main speakers, adjustable continuously between 40 Hz and 140 Hz.

Will the 13.8 by 13.4 by 14.6 inch cabinet fit beside my entertainment unit?

The down-firing cabinet stands 13.8 inches high, 13.4 inches wide and 14.6 inches deep on its feet, so measure that footprint against your available floor space.
