BassLink consists of a 10-inch subwoofer, 10-inch passive radiator, and a 150-watt Class D amplifier 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. Easily mounted in the trunk of a car or elsewhere, BassLink will appeal to consumers who desire more bass but do not wish to extensively modify their vehicles to get it.

"Infinity's engineers have again proven themselves to be leading innovators in the car-audio industry with the creation of this powered system," said Christopher M. Dragon, director of brand marketing, Infinity Mobile. "BassLink is an extremely versatile unit, and it is a great product for anyone who wants quality bass but is reluctant to add aftermarket equipment that may require vehicle modification. It's also a perfect unit for consumers who lease cars and are not able to modify them to accommodate the aftermarket equipment they desire. With this system, Infinity continues to provide consumers who crave heart-pounding bass with the best products and system options on the market."

The system features a servo-control circuit in the amplifier that monitors the voice coil's position in the magnetic gap and limits the amplifier's output to prevent woofer over-excursion. This unique limiting circuit allows the amplifier to operate unchecked as long as the woofer's behavior is linear, unlike conventional limiters that solely consider the amplifier's abilities. The system's servo circuit monitors the back EMF from the woofer to monitor the voice coil's position in the magnetic gap; when it begins to leave the gap, the limiter is engaged.

BassLink offers a fixed 2nd-order high-pass filter that eliminates the possibility of over-excursion below Fb, the resonant (tuned) frequency of the vented box (40 Hz). This allows the excursion-monitoring circuit to focus on the excursion at the more meaningful frequencies at and above Fb. The result of this filter is a significant reduction in distortion compared to an over-driven conventional subwoofer and enclosure combination.

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 100 Hz; variable input sensitivity; and Bass EQ that provides for adjustments between +3 and -6 dB at 40 Hz. BassLink's frequency response in a typical vehicle is 25 to 110 Hz (±3 dB), but this varies according to the vehicle and user adjustments. Infinity reports that at maximum gain, the system can accept inputs as low as 250 mV.

BassLink can accept up to four channels of input -- to provide non-fading bass -- either from line-level signals through four RCA jacks or from high-level signals through a pair of Molex connectors. Infinity supplies two 6-meter color-coded wiring harnesses for high-level signals, 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 the remote turn-on.

Measuring just 14.5 x 12.5 x 8 inches, the sleek system is encased in a sophisticated textured black glass-reinforced polymer enclosure, with an attached aluminum amplifier heatsink. BassLink can be mounted either vertically or horizontally and comes with a two sets of cast mounting brackets to accommodate either mounting option. BassLink will have an MSRP of $499.95.
