Polk MXT90 Atmos/Surround
The Polk Monitor XT90 adds a dedicated height channel to a compatible home-cinema system. It can sit on selected Monitor XT loudspeakers or mount to a wall when the room layout calls for a separate position.
Its angled enclosure uses a bilaminate paper woofer to direct height information towards the listening area. Dolby Atmos, DTS:X and DTS Virtual:X compatibility lets the module handle overhead effects and ambience from a suitable AV receiver.
Plan the XT90 as part of a minimum seven-channel receiver system, then match placement to the ceiling and seating position so the reflected height channel reaches the room as intended.
