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.



High 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.
