Free-Standing RTL Subwoofer

The SAS occupies less than 60 percent of the space of the SCS Subwoofer. The diminutive size of the SAS belies its amazing performance, featuring one of the same woofers used in both the S90i and SCS, with an extension to 30Hz. Its highly efficient and compact Regenerative Transmission Line® design yields fast, dynamic, articulate results with accurate timbre.

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.
