In our
Regenerative Transmission Line TM
subwoofer, the energy from the back side of
the driver is sent along a long, folded path in such a way that its lowest frequencies
arrive back at the front side of the driver in phase, effectively summing to an increase of
6 dB in output. Thus, the energy from both sides of the woofer cone is used in a
productive way, resulting in a substantial reduction in distortion and an effective surface
area double compared to what you would otherwise expect. As an example, the
effective radiating surface area of the two 15” woofers in the STS is equivalent to four
15” woofers in more conventional enclosures.
The results are quite stunning. Low frequencies are strikingly dynamic and responsive,
and integrate quite seamlessly with the fast and detailed Sage Series planar magnetic
hybrids. As an example, the STS is only -3 dB at 15 Hz and can output in excess of 130
dB at 20 Hz.
Unpacking the STS
The Wisdom Audio STS subwoofer is a substantial piece of equipment. Please exercise
caution when unpacking your STS to ensure that you do not strain yourself from its
(perhaps unexpected) weight.
CAUTION
Do not
attempt to lift your STS by yourself.
Unpacking this subwoofer is clearly a two-
person job. It is unwise for a single person to attempt doing so.
Do not
attempt to lift your STS while bending or twisting from the waist.
Use your legs
for lifting, not your back.
Always
stand as straight as possible and keep the STS close to your body to reduce
strain on your back.
