The Klipsch RSA-500 is a single channel amplifier designed to power a passive subwoofer (a subwoofer that has no internal amplifier).
Primarily designed for use with the Klipsch RW-5802 and RW-5101-C in wall subwoofers, it also features custom settings for the AW-800-SW outdoor subwoofer.
This amplifier pumps out 300 watts into an 8-ohm load (one subwoofer module) and 500 watts into a 4-ohm load (two subwoofer modules).
The RSA-500 offers standard input/output connectivity that will support any type of system.
Rack ears are included for fast and secure placement into any standard 19-inch rack.
