    X15 HiQ reference stage monitor The X15 HiQ is an active coaxial system designed as a reference stage monitor. The enclosure features a 3" diaphragm compression driver coaxially-loaded by a low frequency transducer in a bass-reex cabinet. The L-Vents laminar vented ports reduce turbulence and port noise at high levels to increase LF efciency.
