The SUB118 is a compact subwoofer designed to extend the frequency range and power bandwisth of Audio Performance full-range loudspeaker systems. With a cut-off frequency of 45Hz, the SUB118 is made for applications where the reproduction of sub frequencies is of major importance (music, live sound). It consists of one 18" ND long excursion cone driver mounted in a heavily braced band pass enclosure.

The design of the SUB118 is based on band-pass technology. This technology allows relatively compact enclosure to be very efficient in low frequency reproduction and increased power handling without excessive displacement of the loudspeaker.
