Wisdom STS Freestanding RTL® Passive Subwoofer

STS Freestanding Regenerative Transmission Line® RTL Subwoofers establish a new benchmark in subwoofer performance.

This subwoofer from Wisdom achieves significant musicality, timbre and accuracy in the deep bass provided for films. Some customers sought commercial subwoofers for their excellent delivery of the extended bass and high SPL capabilities needed for larger home cinemas and this is now, exactly, what now is provided by Wisdom's STS subwoofer.

This STS, designed also to be use with Wisdom's Architectural Series subwoofers features highly efficient dual 38.1cm or 15" woofers, which yield fast and dynamic results with accurate timbre for unsurpassed musicality.

Each STS can deliver significant SPL, given its 101dB sensitivity, reaching an astonishing SPL capability of 130dB at 20 Hz.

In taking full advantage of the 44.45cm or 17.5" dimension and uncommon shape of the enclosure as well as with the port configurable to any of three sides, the STS offers unprecedented installation flexibility. An external port option even allows for placement in ceiling or floor spaces and even an adjacent room.

A pair of STS subwoofers can be mated to a single Sage Series SA-1 System Amplifier, which can drive two STS units via its single input. Each STS will be able to deliver significant SPL in this configuration, given its 101dB sensitivity and 500W output of the SA-1. However, for large venues or installations where SPLs are required, amplifiers offering much higher output can be used in concert with the STS’ peak power capability of 5,000s to satisfy even the most demanding applications.

The RTL design delivers the unique combination of high sensitivity, high output and low distortion with the uniform and extended responses required. The result is, the STS offers extraordinary power and punch combined with a remarkable level of quickness, tunefulness and realism.
