High tech Bluetooth lets you listen to music with a tap of a finger, playing music from the devices from several rooms over with no interference, up to 40 feet! (other brands 30 feet) 95dB of room filling, crystal clear sound with less than 1% total distortion, it does really make for a nice listening experience. Multiple options for connection: Working for any devices(Phone / pad / Laptop / TV / DVD Player / Network Player / Media Player / PC / MP3 / MP4 / PSP / Etc..) which have Bluetooth function or Stereo RCA output or Stereo 3.5mm output. Built in bass system, it without having external sub woofer, but the bass in most cases sounds like it has an individual small sub along with it! Remote is simple and well made - no annoying prompts or beeps. Included spacer template is a VERY welcome addition and made wall mounting this very easy.
