Subwoofer for home theatre systems

The Acoustic Audio PSW-12 is a powered subwoofer with a 12 inch down-firing driver and a built-in high-efficiency amplifier rated at 500 watts peak. It covers a frequency response of 24 to 250 Hz at 98 dB sensitivity and uses a black ash finished MDF cabinet with internal bracing. Standard RCA and high-level raw wire inputs allow connection to a wide range of receivers and stereo amplifiers.

Suited for buyers adding bass to a surround system

This subwoofer fits listeners who want deep low-frequency reinforcement from a single cabinet with auto on/off sensing, phase control and a variable crossover between 40 and 140 Hz. It is not for systems that require a dedicated LFE channel input, nor for setups that lack either an RCA sub-out or speaker-level outputs on the source component.

Deciding spec: 500 watts peak power

The combination of peak amplifier power and driver size determines whether the unit can deliver the output level a room needs. Buyers should match the 500 watt peak figure and 24 Hz low-end extension against their receiver’s subwoofer output capability and the listening space volume.

Questions about this item

How much floor space does the 13.8" high cabinet with 13.4" width and 14.6" depth need?

The standing subwoofer measures 13.8 inches tall by 13.4 inches wide by 14.6 inches deep, so allow at least that footprint plus a few centimetres of rear clearance for the downward radiating slot port to breathe.

Which cable do I plug into the receiver's subwoofer output, and where does it go on the sub?

Use a standard RCA cable from the receiver's dedicated Sub Out into either of the dual low-level RCA inputs on the back panel; the auto on/off circuit will wake the amplifier when it detects a signal.

Will the 12-inch PVA-treated cone or the built-in 250 W nominal amplifier need periodic service?

The driver and integrated amplifier are sealed inside the CARB-compliant MDF cabinet with internal bracing and have no user-serviceable parts; normal dusting of the black ash finish is the only upkeep required.
