S181 Compact Subwoofer

The x is a compact subwoofer designed for sound reinforcement. The single DL18mt 10-inch woofer is loaded into an enclosure based upon manifold principles, yielding efficient performance in the 50 Hz to 200 Hz frequency range. The design creates a bandpass for the subwoofer’s output, providing a natural rolloff of 24 dB per octave at 200 Hz.
