The design that keeps technology in the forefront The PD-6C is capable of putting high fidelity throughout the home in a compact 6" In-Ceiling version. Each PD-6C contains a BG's patented Neo3PDR Neodymium planar ribbon tweeter that delivers an extremely broad, well-defined soundfield over the entire listening area. Further to having the NEO-3PDR tweeters amazing dispersion and resolution, the PD-6C makes use of the innovative NRT, (NeoRadiaTechnology) motor structure with high-excursion capabilities and very low distortion. The high-tech woofer design makes use of a small NRT, Neodymium magnet structure to provide an acoustically-transparent woofer chassis. This dramatically improves midrange clarity by eliminating sound reflections directly behind the woofer. The superior Kevlar cone woofers used in the PD-Series not only take advantage of the NRT for sensational two-channel clarity, but are also capable of reaching and maintaining the extreme output levels associated with home theater applications.
