12-inch Active Subwoofer Speaker

The Superlux molded powered subwoofer is the ideal solution where big sound and compact portability are required. Combining the amazing low-frequency performance of an subwoofer driver with high-efficiency 500 Watt amplifier channel and an electronic crossover, the SF12AS eliminates the need for a separate crossover to drive a full-range system. Through the satellite speaker output, the performance match active full range speaker can be connected to subwoofer speaker. A line level XLR output is also provided for daisy chaining to powered speakers or additional power amps. Combing with full range speaker, the active speaker creates an extended low frequency response and comes a big full sound from a very small package. The result is a compact, self-contained 3-way system that sounds much bigger than it looks.
