Powered Free-Standing RTL Subwoofer

The compact size and aspect ratio of the SCS allows it to be placed in areas where other in-room subwoofers will not fit, offering customers a unique freestanding subwoofer option – one that can actually be hidden. The SCS is powered by a 400-watt internal amplifier and is capable of 120 dB @ 25 Hz. The dual 5-inch x 7.5-inch woofer design yields an equivalent active cone area of 13 inches and is taken directly from the larger S90i in-wall subwoofer.

The Regenerative Transmission Line®

Regenerative Transmission Line® designs yielded the unique combination of high sensitivity, high output, and low distortion with the uniform and extended response we required. The result is extraordinary power and punch combined with a remarkable level of quickness, tunefulness and realism.
