Insanely powerful H.O. (High Output) systems deliver very high SPL while retaining excellent sound quality.
HO models use our innovative, chamber-coupled port design. The slot-port wraps around the inner enclosure and terminates on the mounting plane of the woofer. This provides the necessary surface area and port length to maximize the performance of the driver, while also coupling the port output and direct woofer output to radiate together into the listening space.
