SongSub VLD (very low distortion)...
another price/performance breakthrough -
a
subwoofer for use with SongTower QWT's
With the introduction of the SongTower QWT's complete,
we turned our attention to a matching subwoofer.

12" high-excursion
aluminum cone driver |
500 Watt RMS plate
amp |
12" full suspension
passive radiator |
It takes a very capable subwoofer to keep up with the
sound quality of the SongTower QWT's. So we pulled out all the stops to produce
a reasonably-priced subwoofer with great performance characteristics.
Check out the SongTower's
specifications/cost.
the design
the driver
12" Cast Frame high-excursion woofer with black anodized
aluminum cone. The motor has three different shorting paths that dramatically
reduce voice coil inductance and motor distortion. Distortion levels are lower
than nearly all other high excursion subwoofers on the market.
the passive radiator
12" Cast frame - full suspension passive radiator, mass
tuned, with 22mm of one-way Xmax capability.
the plate amp
500 Watt RMS Class D BASH type high efficiency amplifier
with fully adjustable 4th order lowpass crossover. The amp features a
continuously-variable phase control (not a 0/180 switch like on many plate
amps), full parametric EQ to adjust for room response, adjustable crossover
with bypass switch, subsonic filter to extend low-end response, an auto-on
feature and more.
system performance
With this tuned enclosure and this amplifier, the woofer
remains within its linear operating range at all frequencies above 20Hz at the
full 500 Watt output of the amplifier. This linear performance, coupled with
the shorting rings inside the motor make this a "Very Low Distortion" (VLD)
subwoofer when compared to even many much more expensive subwoofers on the
market today.
Bass Extension - In an anechoic environment this
subwoofer has a 1 Watt Nearfield -3dB point of 22Hz. In most rooms bass will
extend to approximately 18Hz due to typical room gain.
Output - Maximum
half-space output is 112 dB at 30Hz, 109 dB at 25Hz, 102 dB at 20Hz (Without
Room Gain), with linear output at very low levels of harmonic distortion.
SongSub options and pricing
Normally, a subwoofer of this quality will retail around
$2000. But because you are purchasing direct, you can expect to pay
considerably less. SongSub subwoofers are available in standard oak, curly
walnut, curly cherry, curly maple, mahogany and satin black lacquer and are
priced at just $995. See a selection ofSongSeries
veneer samples. If purchased in conjunction with a pair of SongTower QWT's,
the price is $895, a $100 savings. Custom finishes are also available starting
at $1095 (premium veneers extra).
