At the heart of the Polk Audio MXT20BK Bookshelf Speakers is a precision-engineered 1-inch Terylene dome tweeter that delivers crisp, natural high frequencies without harshness or distortion.

Built with low-resonance MDF cabinets and precision internal bracing, these speakers minimize unwanted vibrations and coloration. The rear-firing bass port enhances low-frequency extension while maintaining accurate sound reproduction.
