KENWOOD KSC-SW11

Kenwood KSC-SW11 Compact Powered Enclosed Subwoofer for CAR
The KSC-SW11 offers acceptable levels of sound at 75W RMS from it’s compact 8” subwoofer and built in amplifier. Also featuring a wired low-pass crossover (LPF) to allow the user to filter certain frequencies out between 50 – 125Hz.
On the same wired remote control there is also a gain control (which acts as a volume control for the subwoofer) and a phase control, which is useful given that the subwoofer will be on a different plane to the rest of your speakers.75W RMS might not seem like a lot, especially compared to trunk based subwoofers that range from 250W upwards with many being around 500W, but when you consider that this subwoofer is designed to be in the same cabin as the listener and often right under your seat, it gives a good amount of punch.
75W can add a sufficient amount of bass to a system where high volume is not a concern and it will make most music sound vastly more immersive. Likewise, for those that already have a trunk based subwoofer, the extra punch up front can compensate for lacking door mounted speakers.

SOUND STORM LABS LOPRO 8
SSL say their shallow design amplified subwoofer is capable of 400W RMS and drops to a very low 20Hz, which is a big claim and it’s hard to see this subwoofer actually hitting 20Hz. It’s interesting to see a subsonic filter included with this amplifier, which can be very useful. If a subwoofer is incapable of playing a particular frequency, they can bottom out leading to a flat sound.
Essentially, a subsonic filter will tell it to ignore frequencies below a certain range (in this case can be set between 20 – 50 Hz).

Short of using specialised sound and voltage measuring equipment, it’s impossible to tell what this subwoofer actually puts out (it’s worth pointing out that this is the case for EVERY speaker on the market).
In terms of the unit itself, it’s a shallow mount design that will allow it to fit snuggly under a seat. There’s an included inline cable for volume level as with the other products with all other controls, including LPF, subsonic filter and gain controls on the side of the unit.
There’s a 6-year warranty, but nobody buys something just to use the warranty and if it doesn’t last, there’s no point. In the sub $150 range, it’s difficult not to be curious, but don’t expect the world in terms of quality.
