Acoustically damped, UV-resistant polypropylene cone
Every Club speaker's woofer cone is designed to deliver clean, non-resonant sound quality, while standing up to the demanding heat and humidity of the car environment.
Plus One™ woofer cone architecture. Harman's patented (US patent #7,548,631) Plus One™ cones provide more overall speaker-cone area than other cones in its class — the result is higher sensitivity, increased low-frequency output and greater musical character.
Club speakers play smooth, clear high frequencies with excellent dispersion, thanks to the PEI balanced dome tweeters.
