The THX® Speaker Series has been engineered to deliver the highest level of accuracy and reproduce all the dynamics and detail of the best home theater soundtracks and music. Each speaker has been THX certified, ensuring optimal frequency response, dispersion, and low distortion. THX certification ensures that the sound from the speaker is as the audio engineer intended. The THX-365C features a three way design, so dialog sounds crystal clear whether you are on axis or off. Premium drivers, THX certification, a sophisticated crossover network, and an HDF cabinet ensure that you’ve never experienced home theater sound this dynamic, detailed, or immersive. PREMIUM DRIVERSCrystal Clear Dialog. Silk Dome Midrange. Silk Dome Tweeter.Featuring carefully selected drivers that deliver a flat frequency response in the listening window, the THX-365C features two 6.5" (16.5 cm) woofers, a 2" (5 cm) silk dome midrange, and a 1" (2.5 cm) silk dome tweeter. The 6.5" high excursion woofers utilize long pulp paper cone, NBR surrounds, and feature shorting rings to keep distortion at a minimum, so dialog can come through accurately and cleanly. PRECISION CROSSOVER NETWORKThe THX® speaker series feature carefully selected fourth order Linkwitz-Riley crossover network acoustic filters. This sophisticated crossover minimizes sonic frequency overlap, reduces distortion, and is an excellent choice to minimize off axis response errors near the crossover frequency.PREMIUM BUILT CABINETHigh Density Fiberboard. High Quality Binding Posts. Magnetic grille.Each speaker cabinet is built with HDF, not MDF material. HDF isbetter damped than MDF, resulting in a sonically inert cabinet. Internal bracing has been strategically placed inside to limit unwanted cabinet resonance that could color the sound. The center channel speaker is outfitted with high quality binding posts, and the bottom has a built-in pad to help isolate it from the surface it is placed on.
