RTL® Subwoofers


The Goal: Create a low frequency system that could sustain dynamic contrasts and low coloration in the bass
range that was comparable to our world-class planar magnetic transducers.

The Answer: Regenerative Transmission Line® Subwoofers


In-Wall / Ceiling / Baffle / Floor / And Floor-Standing

  • S55i
  • S90i
  • S110i
  • SAS
  • SCS
  • SCS-2
  • STS
  • S10
  • SUB1

The S55i is a strong performer, featuring the quickness and tonality all our RTL subwoofers are known for, with bass extension to 40Hz.

The S90i’s superb performance characteristics, which include flat response to 20 Hz with usable in-room energy down to 17 Hz, and outstanding dynamic capability and accurate timbre reproduction.

The S110i follows closely in the footsteps of our flagship model STS, widely recognized as a benchmark in subwoofer performance.

SAS belies its amazing performance, with extension to 30Hz.

The SCS is powered by a 400-watt internal amplifier and is capable of 120 dB @ 25 Hz

The SCS-2 is capable of 120 dB @ 25 Hz

The STS' highly efficient dual 15-inch woofers yield fast, dynamic results with accurate timbre for unsurpassed musicality

The S10 (10”) Passive Subwoofer is a versatile unit capable of producing powerful clean bass from an incredibly compact cabinet. Convertible from freestanding upright to down-firing or up-firing installation, the ultra-compact design can easily be hidden under sofas or cabinets.
