XD-series is a range of next generation subwoofers. Featuring US-patented enclosure design, a combination of assymmetric horn combined with and 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 due to three acoustically tuned segments make a huge difference to how the smallest nuances are performed. The reduced Xmax will also maximize the life of the driver.

All these features in a compact size box with no need for complicated reinforcement structures in the enclosure makes the units even liter weight and easier to handle. All XD-series enclosure feature rigid birch plywood construction and weather proof semi-matt paint finish.
