Insanely powerful H.O. (High Output) systems deliver very high SPL while retaining excellent sound quality
--------------------------------------------------------------------------------
W6v2 H.O. Wedge™
Based on the design of the W7 High Output systems, the W6v2 “H.O.’s” are designed to perform at serious output levels while retaining exceptional sound quality. The W6v2’s also have the benefit of smaller enclosure requirements making these some of the smallest of all the “H.O.’s”.
Each is properly sized and tuned to the optimum ported alignment for the 12W6v2 or 10W6v2 and is shipped wired, loaded and ready to install. Both models use our patented, chamber-coupled port design. The slot-port wraps around the inner enclosure and terminates just above the woofer. This provides the necessary surface area and port length to maximize the performance of the W6v2’s. The recessed mounting baffle also provides protection for the woofer.
Available Models:
HO110R-W6v2
HO112R-W6v2
