Polk Audio is throwing its hat into the ring of compact, affordable sound bars. It's an already crowded field that's getting a bit more competitive, thanks to the Polk MagniFi Mini ($299), an "ultra-narrow soundbar" that also includes a slim wireless subwoofer, both designed for smaller living spaces. The soundbar's compact form measures 13.4 inches long and 3.1 inches high, and includes four 2.25-inch drivers and two 12mm tweeters for the main unit. Features include Bluetooth, networking (with Google Cast) and HDMI with Dolby Digital decoding. Additionally, Polk's patented sound modes deliver clarity at low volumes, as well as increased speech intelligibility. Look for the MagniFi Mini to launch in October.
