The SW1800A is a compact powered manifolded subwoofer designed to provide sub-bass support for the compact AX800A compact line array, and features some of the most advanced technologies for low frequency reproduction. The manifolded bandpass design uses manifold loading of the front side of the speaker cones to maximize the mutual coupling between the two drivers. This innovative configuration does not use any large resonant cavity to load the speakers, but very compact cavities in order to obtain advantages in terms of definition, both at the lowest end and the upper bass.
