With a total weight of just 2.8 kg, the SL300A Active System is the special sound solution for small vehicles in the spare wheel recess (up from 15 inches). The low weight is made possible by the use of unbreakable ABS plastic, which has excellent soundproofing properties. The case features a specially developed 13 cm subwoofer with a strong magnet and a high-performance, very long wound 38 mm voice coil. Thanks to the very high linear performance and the ingenious bass reflex channel, this compact system produces bass like a "BIG ONE"! In addition to the built-in amplifier for the bass, it is possible to connect two more full range speakers to the free stereo amplifier outputs, e.g. already existing factory speakers with more power supply.
