The Harman Kardon Nova Stereo Streaming System ($300) puts big sound in a small package. The Nova’s are a 2.0 wireless stereo system. The speakers are driven by 40 watts of clean Harman Kardon power. Each speaker have a 2.5″ driver, a 1.25″ tweeter, and Harman DSP which improves soundstage and voicing. The system is compatible with most devices via analog, optical, or Bluetooth connections. For serious listening you’ll need to pair a sub with these guys, but the 70Hz-20KHz frequency response should get you through most situations.
