Lots of good stuff packed into this slim soundbar. Polk Audio’s MagniFi Mini AX manages to wedge in support for Dolby Atmos & DTS:X, plus a subwoofer & 5 speakers. It’s got ports for ARC HDMI and optical inputs & also supports audio streaming via Bluetooth, AirPlay 2, SpotifyConnect & Chromecast. All that & it measures just 14.5” long.
