A five-driver, three-way design, the Performa F52 includes a trio of high performance 6½-inch woofers that incorporate our exclusive Organic Ceramic Composite cone technology, which provides the ultimate combination of rigidity and lightness. Featuring butyl surrounds and high strength magnetic motor structures, together these woofers provide the deep bass response commonly associated with a much larger single driver, along with low distortion and wide frequency response, allowing a much narrower cabinet profile. The 5¼-inch OCC cone midrange driver is similarly equipped, and is housed in its own sub-enclosure within the F52’s elegant cabinet, which is constructed of thick and acoustically inert MDF and features substantial internal bracing for added rigidity.
