The SWA500's standard chassis width lets you stack it neatly with your other audio/video components, or you can hide it away in a cabinet to reduce room clutter. This stable amplifier can also power a pair of either the CSW100s or CSW200s, for even bigger, stronger bass.

Features

Overview: The SWA500 amplifier is designed to be used with the following Polk in-floor/in-ceiling subwoofers: CSW100, CSW155 and CSW200. One SWA500 amplifier can power up to two subwoofers at the same time.

Note: The SWA500 cannot be used to power any other subwoofers.

Class D Amplifier: The SWA500 has a hybrid Class D amplifier that produces 250 watts RMS into 8 ohms and 500 watts RMS into 4 ohms.

SPEX Cards: The SWA500 comes with three SPEX Cards, one for the CSW100, one for the CSW155 and one for the CSW200. Each SPEX Card configures the EQ, crossover, and power control circuitry to match the appropriate subwoofer.

Variable Crossover: The amplifier has a built-in variable crossover that makes it easy to achieve a seamless blend with the main speakers, while the 24dB/octave low-pass filter prevents the subwoofer from being easily localized by the ear, increasing placement flexibility. The crossover point may be adjusted from 40-120 Hz.

Protection Circuitry: The SWA500 offers thermal, short circuit, and over-current protection.

Auto On/Off Sensing: In Auto mode, the amplifier automatically turns on when it senses a signal and turns off when a signal is not present.

Controls

Front Panel Controls:

  • Low-pass Knob: allows you to adjust the low-pass crossover point from 40-120 Hz
  • Volume Knob: allows you to adjust the volume level up or down until the bass level of your subwoofer matches the bass level of your speakers

Rear Panel Controls

  • Phase Switch: switches the polarity of the two speaker outputs; the correct setting is that which yields the fullest bass
  • Power Switch: allows you to choose one of the following power modes: Standby, Auto, or On

Connections

Rear Panel Connections:

  • Speaker Out (1 and 2): gold-plated binding posts; the binding posts are not 5-way because a plastic collar prevents their use with spade lugs. Both speaker outputs are wired in parallel and allow you to connect one or two subwoofers to the amplifier
  • Speaker In: gold-plated binding posts; the binding posts are not 5-way because a plastic collar prevents their use with spade lugs
  • Line In (filtered): left and right RCA audio jacks; use this configuration if you wish to set the subwoofer crossover point using the SWA500's low-pass control knob on the front panel
  • LFE In (unfiltered): single RCA audio jack; in this configuration, the SWA500's internal low-pass filter and front panel low-pass control knob will be bypassed
  • Line Out: left and right RCA audio jacks
  • SPEX Card: slot for the supplied SPEX Cards; a 7-pin connector plugs into the card and the card bolts into the back panel of the amplifier

I don't think this would be a good choice for your application, it is best suited to be used with the polk audio subwoofers listed in it's description.

The Polk Audio SWA500 amplifier is designed specifically to drive the Polk CSW100, CSW155 and CSW200 in-floor/ceiling subwoofers. It cannot be used to power any other subwoofer model(s). If you would like to explore other options that may work with your subs, feel free to contact an Advisor directly by phone (1-800-324-9695) or online chat. I hope that helps!
