Design & Build Quality of the Polk Monitor XT90

Polk Audio’s design philosophy blends precision engineering with aesthetic simplicity. The Polk Monitor XT90 features a compact, acoustically optimized enclosure that easily fits atop compatible XT20, XT60, or XT70 speakers. Alternatively, they can be wall-mounted to suit your room layout.

Each speaker sports a clean matte black finish with subtle curves that blend seamlessly with any interior decor.
