Powered, 8" (200mm) car audio under seat woofer system Proprietary, shallow-profile woofer The 8" (200mm) woofer in the BassLink SM is designed specifically to provide low distortion and great bass performance in an ABS enclosure with a remarkably compact footprint. Efficient Class D amplifier The amp that powers the BassLink SM produces minimal heat, and it doesn’t require a lot of current from the car’s electrical system. Intelligent electronic design The BassLink SM employs high-pass filters and limiters that deliver exceptional at-the-limits performance. Crossover control A manual crossover control (50Hz – 120Hz) lets you adjust how much upper bass and mid-bass the BassLink SM produces. Fine-tune the crossover to achieve a smooth transition from the BassLink SM to the rest of the system’s speakers. Flexible EQ adjustments Level control adjusts the BassLink SM’s volume to the other speakers in your system, while Bass Boost control lets you minimize peaks or dips in bass frequencies in your car’s acoustic environment. Line- and high-level inputs For added installation flexibility, the BassLink SM features both line- and high-level inputs. If you use the high-level inputs to connect the BassLink SM to the head unit, an input load switch lets you switch from “Low” to “High” to achieve optimum results. Wired, remote level control capability The BassLink SM is compatible with the RBC Remote Bass Controller (sold separately), which enables you to control the level remotely.
