In-Wall RTL Subwoofer with Port Extension Kit

The S110-f/c follows closely in the footsteps of our flagship model STS, widely recognized as a benchmark in subwoofer performance. In installations where you need to vent/port the subwoofer into a space from the attic, crawlspace, or an adjacent room the S110-f/c is the answer. The S110-f/c has an incredible maximum SLP of 128dB at 30Hz.

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.
