The Polk Audio VM20 speakers are sold as a pair of L/C/R satellite loudspeakers and feature the same emphasis on polished design as the entire VM Series. The VM20s feature dual 4-inch planar bass radiator subwoofers and dual 4-inch dynamic balance mineral-filled polypropylene cone drivers. As in the VM30 speaker Polk outfits the VM20s with a 1-inch ferro-magnetic fluid-cooled aluminum dome tweeters for accurate, reliable high-end frequency sound. The VM20s offer a 70Hz-26kHz frequency response and optional floor or table stands for mounting. The Polk VM20 speakers can be matched with Polk's PSW111 or DSW MicroPro subwoofers for optimal performance but also function on their own.
