        Product details

        GRS K-33-4 Replacement 15" Woofer for Klipsch Speakers

         

        The GRS K-33 was designed to have the same performance in free-air as the original in order to have the same performance in-cabinet for worry-free replacement.

         

        The engineers at GRS understand that while performance is important when selecting replacement drivers for a restoration project, aesthetic is close behind in what dictates an appropriate replacement. Using the same materials and colors for paper cone, dustcap, and triple-roll surround, down to the design of the stamped frame, GRS guarantees mis-matched components won't get in the way of enjoying your favorite Klipsch heritage cabinets.

         

        DIY-ers who do not own any of the classic cabinets will appreciate the high-sensitivity and subdued midrange for easy crossover and cabinet design.

        Da ich vier Klipschörner habe, hatte ich mir zu Testzwecken einen GRS K 33 bestellt und eingebaut.
