Designed specifically for surround use in home theater applications, the R-5650-S II employs a refined 6.5-inch Cerametallic woofer for even tighter bass and dual 1-inch titanium compression drivers (tweeters). The addition of a Linear Travel Suspension to the tweeters increases high frequency detail and smoothness. Because of its patented horn array which is two vertically stacked Tractrix Horn-loaded tweeters pointing in opposite directions, the R-5650-S II outperforms conventional designs by maximizing diffusion clarity and efficiency while minimizing room interactions that blur sonic detail.
