The S55i can be mounted in-ceiling, in-wall, under risers, in closets, and on floors. It is a rare example of a custom-centric design that offers competitive results versus the finest freestanding options. The S55i is a strong performer, featuring the quickness and tonality all our RTL subwoofers are known for, with bass extension to 40Hz. Its size makes it well suited to being custom-installed and thereby hidden behind its small paintable grill and bezel.
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.
