S55i
In-Wall (2×4) Regenerative Transmission Line® RTL Subwoofer
The S55i can be mounted in-ceiling, in-wall, under risers, in closets, and in 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.
