Free-Standing RTL Subwoofer

The STS establishes a new benchmark in subwoofer performance. Until now, there hasn’t been a subwoofer that is capable of delivering both unsurpassed musicality, and the high SPL and accurate, extended bass desired for the ultimate in movie performance within large residential spaces. The STS’ highly efficient dual 15-inch woofers yield fast, dynamic results with accurate timbre for unsurpassed musicality. Each STS can deliver significant SPL, given its 101dB sensitivity, reaching an astonishing SPL capability of 130dB at 20 Hz.

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.
