XD-series is a range of next generation subwoofers. Featuring US-patented enclosure design, a combination of assymmetric horn combined with band-pass loading gives the subwoofer high efficiency, speed and extremely low distortion figures while minimizing the off-band problems common to bass reflex and direct radiating designs. The usable frequency range also increases compared to common designs together with detail and transient output through out the whole usable bass region. The extremely accurate cone control and reduced Xmax will also maximize the life of the driver.

XD18Ci is covered with water resistant semimatt black coating and optional rigging hardware is available on request.
