As some of you may know, my car was broken into recently and I've been left without low-end frequencies for the past couple of months.
In short, I've been looking for a replacement active bass box that I can remove as easily as the last one (evidently too easy for some :( ) , that is small enough to retain bootspace with the right frequency response range. I'm not a full-install kinda guy, and in light of some recent threads about the Kenwood unit, I thought that I may as well get something different to review for the club. So I've ordered one of these:

Hopefully it'll perform as well as they say it does, to be honest I'd be surprised if it does indeed produce the advertised 20Hz. Here are the specs... what do you audio boffins think?
10" subwoofer and 10" passive radiator with built-in amp
Dimensions (H x W x D): 14-1/2" x 12-1/2" x 8"
Power Output: 200W
Frequency Response (±3dB): 20Hz - 100Hz
Variable Bass EQ: +3dB to -6dB at 45Hz
Variable Electronic Crossover: 70Hz - 100Hz
BassLink can be mounted vertically or horizontally using its unique mounting system.
BassLink provides user-adjustable input sensitivity, crossover frequency and bass-boost. This allows BassLink's performance to be optimized for any installation.
Four low-level inputs provide nonfading bass.
High-level inputs allow interface with most factory systems.
200-Watt Class-D amplification.
Rigid-polymer chassis withstands the rigors of the road.
SUPPLIED WITH BASS CONTROLLER.
Designed to deliver low frequencies in virtually any car audio system, BassLink truly has universal appeal. Small in size but big in output, BassLink requires a mere .75 cubic feet of trunk space yet produces enough bass to wake up the neighborhood.
BassLink consists of a 10-inch subwoofer, 10-inch passive radiator and a 200-watt Class D amplifier housed in a rigid polymer enclosure, all carefully engineered to work together as a unique, integrated system. The extremely versatile BassLink accepts both speaker- and line-level inputs, and it provides an internal low-pass filter, proprietary signal processing and abundant amplification.
The BassLink system features a servo-control circuit that continually monitors the voice coil’s position in the magnetic gap and prevents the distortion that occurs when a conventional woofer is overdriven. By integrating cone-excursion information with the instantaneous demands of the music, BassLink can extract loud and deep bass from an enclosure smaller than any before.
BassLink includes a fixed, 2nd-order, high-pass filter that eliminates the possibility of over-excursion below Fb, the resonant (tuned) frequency of the vented box. This allows the excursion-monitoring circuit to focus on the excursion at the more meaningful frequencies at and above Fb. The result is a significant increase in bass output.
User-adjustable controls allow listeners to set the system’s response to achieve optimum performance based on the vehicle’s cabin gain or transfer function. These controls include: a 0- or 180-degree phase switch; a continuously variable electronic low-pass filter that is adjustable between 70 and 100Hz; variable input sensitivity; and Bass EQ that provides for adjustments between +3 and –6dB. BassLink’s frequency response in a typical vehicle is 20 to 100Hz (±3dB), but this varies according to the vehicle and user adjustments. At maximum gain, the system can accept inputs as low as 250mV.
BassLink can accept up to four channels of input – to provide nonfading bass – either from line-level signals through four RCA jacks or from high-level signals through a pair of Molex connectors, allowing BassLink to be easily connected to OEM systems. If using the speaker-level inputs, an audio-sense circuit will turn on the amplifier whenever a signal is present. If the RCAs are used, a 12-volt, remote-turn-on lead is required. The system has barrier strip connections for power, ground and remote turn-on.
Naturally, I'll let you guys 'n' gals know how much bang for buck it gives for the princely sum of £145.
