About the Klipsch RSA-500

Power your passive Klipsch in-wall subwoofer

Klipsch's RSA-500 makes the perfect companion to the company's RW-5802 II passive in-wall subwoofer — a combination that provides deep, satisfying bass without taking up any floor space.

More details on the Klipsch RSA-500

Product Research



Overview: The RSA-500 amplifier is designed to be used with either the Klipsch RW-5802 in-wall, RW-5101-C in-ceiling, or AW-800-SW outdoor subwoofer. A Sub EQ Selector on the rear panel specifies which subwoofer(s) you're using. One amplifier can power up to two subwoofers at the same time.

Amplifier: The RSA-500 is a BASH (Bridged Amplifier Switching Hybrid) amplifier design that produces 300 watts RMS into 8 ohms and 500 watts RMS into 4 ohms (two subs). The Dynamic Power rating is 875 watts into 8 ohms.

Variable Crossover: The amplifier has a built-in variable crossover, making it easy to match the subwoofer with the main speakers. The crossover point is continuously variable from 40 Hz to 120 Hz.

Power Mode: The power mode switch has three settings:

  • Trigger: the amp turns on when there's a DC voltage (5-30 volts) on the 3.5mm Trigger Input jack
  • Auto: the amp turns on when there's an audio signal input on the speaker level or line level inputs
  • On: on whenever the master power switch is on


Front Panel Controls:

  • Crossover: rotary knob; adjust the low-pass crossover point from 40-120 Hz
  • Volume: rotary knob; adjust the volume level of the subwoofer to match the other speakers

Rear Panel Controls:

  • Phase Switch: switches the polarity of the two speaker outputs; the correct setting is that which yields the fullest bass
  • Sub EQ: set the EQ switch to match the sub in the system; RW-5802, RW-5101-C, or AW-800-SW
  • Power Mode: choose one of three power modes: Trigger (amp turns on when there's a DC voltage, 5-30 volts, on the 3.5mm Trigger Input jack), Auto (amp turns on when there's an audio signal input on the speaker or line level inputs), or On
  • AC Main: master power switch; on/off


Rear Panel Connections:

  • Speaker Output (1 and 2): 2 sets of gold-plated 5-way binding posts; the speaker outputs are wired in parallel and allow you to connect one or two subwoofers to the amplifier; the posts will accommodate up to 12 gauge bare wire
  • Speaker Input: gold-plated, stereo 5-way binding posts
  • Line Input (filtered): left and right RCA audio jacks; use this configuration if you wish to set the subwoofer crossover point using the RSA-500's low-pass control knob on the front panel
  • LFE Input (unfiltered): single RCA audio jack; when using this input the RSA-500's internal crossover is bypassed
  • Line Output: left, right, and LFE RCA audio jacks (unfiltered)
  • Trigger Input: 3.5mm mini-jack
