The SUB1000 is a high power compact subwoofer cabinet designed to extend the frequency range and power bandwidth of Audio Performance full-range loudspeaker systems.With a cut-off frequency of 25Hz, the SUB1000 is made for applications where the reproduction of sub frequencies is of importance (music, sound effects).
It consists of two long excursion 21-inch ND cone drivers mounted in a heavily braced vented enclosure capable of accomodating up to 6'000W of program power.
It operates as a complete system with the AP44M20 amplifier. When stacking several cabinets is necessary, the direct radiating loading of the SUB1000 provides the optimal use of the coupling effect to increase the low-end sensitivity of a system. The enclosure is black epoxy painted, fitted with handles. The front is protected by a heavy duty metal grill covered with charcoal grey foam inside-
