Multidimensional audio done right

Take full advantage of dolby atmos & dts:x
Enjoy the full multidimensional experience of Dolby Atmos, DTS:X and DTS Virtual:X content. The Monitor XT90 was designed to take full advantage of these format’s height audio channels and will reflect sound off your ceiling to add a true third dimension to the sound field of your home theater.

Flexible placement for premium 3d sound
Whether mounted on your wall or placed atop a shelf or select Monitor XT Series loudspeakers, Monitor XT90 set up is easy. They're designed to fit perfectly on top of the Monitor XT20, XT60 and XT70, and they also feature built-in keyhole slots for wall mounting.

Works with any dolby atmos or dts:x compatible receiver
The MXT90 will act as a height channel when paired with any 4- and 8-ohm AV receiver that provides a minimum of 7-channels and that supports Dolby Atmos or DTS:X. You can also use the MXT90 with vintage receivers that have DSP and outputs for ambience speakers.

Polk Precision
Built for pure listening
All Monitor XT models are made for the enjoyment of pure sound: Their nickel-plated binding posts guarantee a direct, lossless connection; low-resonance, critically braced, MDF cabinets isolate the sound of the woofer without adding unwanted resonances; and their removable, precision-fit grilles minimize sonic interference.
