Plus One (patent pending) woofer cones - The P8652 uses a cone with more surface area than competing models of the same size. The benefit is increased bass output and increased efficiency. Computer-optimized voice-matched passive crossover-The P8652 comes equipped with an outboard crossover that has been voice-matched to ensure optimum imaging, clarity and detail. Pure-titanium edge-driven dome tweeters - These are not commonly used miniature cone tweeters, but full edge-driven domes like those found in high end home audio loudspeakers. The benefits of this full edge-driven topology are reduced distortion at high output levels and superior integration with the mid/woofer. The P8652 features Ominpivot, allowing tweeter direction to be maximized for optimum imaging. New HCL cone material - This breakthrough material consists of two woven glass fiber layers with an epoxy-coated Nomex honeycomb core. This cone delivers on what is claimed by many and achieved by few. It is exceptionally stiff, yet lightweight. The benefits of which are increased efficiency, exceptional midrange clarity and lower distortion at high output levels. Oversized voice coils and spider integrated tinsel leads - The P8652 features a voice coil larger that what is found on competing models of the same size. This larger voice coil increases power handling while minimizing distortion. The spider integrated tinsel leads greatly enhance reliability and eliminate audible tinsel lead slap.
