Packing in Audyssey's awesome EQ and BassXT sound processing technologies, the Media Speakers were created to deliver great sound without dominating your desk space. That's why there's no subwoofer. Audyssey opted to rock with passive bass radiators and the aforementioned BassXT tech to make sure your music bumps that way it's supposed to. Aiding in that quest is the array of inputs and outputs which feature a traditional 3.5mm input as well as digital optical audio inputs. No matter what device your media is on, these speakers will make sure it sounds good.
