The H Series Minimum Reflection design significantly reduces sound wave reflections and the resulting sound coloration that occurs with conventional bracket-mounted "box" type speakers. Wall- or ceiling-mount installation is fast and easy using standard electrical gang-boxes, and you can rotate and aim the loudspeaker components without altering the enclosure’s external appearance. Each H Series speaker has a paintable grille and features a high quality Ferrofluid-cooled dome tweeter, Neodymium woofer, 70.7/100 V matching transformer and removable terminal block.
