The EVP-X15 is a 15 inch direct radiating powered subwoofer. A built in 600 watt (peak) amplifier accepts stereo or mono line level inputs.These line level inputs are summed before being sent to the internal amplifier allowing the subwoofer to operate in stereo systems using a single subwoofer. The subwoofer features a pair of integral 100Hz, 24dB/Octave crossovers to send a high pass, balanced, line level stereo signal to a pair of powered satellite full range speakers or an external amplifier for passive satellite speakers. A speaker level 1/4” jack is also provided for use in applications, such as those employing powered mixers, in which it is more practical to bring a full range speaker level signal to the subwoofer.
