is this wireless, bluetooth compatible ?

According to the Klipsch website this model is not compatible with the WA-2 or WA-3 wireless subwoofer kits. They sold a couple of models a few years back that came with the wi-fi piece. Keep in mind Klipsch subs, IMO, are fantastic. If you've got a soundbar or receiver near by they will both connect to this sub via cable and you can use your Bluetooth through the receiver or soundbar (usually)
