    The SW2100P is a very compact Band-Pass/Bass-Reflex subwoofer providing high output and extended low frequency response. It is equipped with a single 21” neodymium transducer with a 4” ISV voice coil, large displacement suspension system, and composite reinforced, water repellent cone, able to provide clean and undistorted LF reproduction at very high SPL.
    The loudspeaker is designed with a unique motor featuring a high grade neodymium magnet assembly in a structure optimized for thermal and magnetic efficiency. Its features include a large displacement suspension system which, in conjunction with a composite reinforced, straight ribbed cone and the proprietary Double Silicon Spider (DSS) technology, allows an ultra-linear piston action and provides full mechanical control across the entire working range. The 100mm (4 in) state-of-the-art voice-coil utilizing Interleaved Sandwich Voice coil (ISV) technology, provides high levels of thermal stability and durability. The ISV technology achieves a balanced linear motor unit exerting an exceptionally high force factor.
    The phenolic birch plywood cabinet is equipped with pole mount socket, stacking feet, flush handles, and heavy duty wheels to enable easy handling and transportation.
    It will deliver high level and extended low bass performance from a very compact cabinet, and thanks to the integral pole mount socket partners well with any of the ED point source and AXIOM line array loudspeakers in any audio applications, while its small size enables it to be easily fitted into tight venue spaces.
