Stream high-quality audio with the Onyx Studio 3 Wireless Speaker from Harman Kardon. This speaker features Bluetooth connectivity for streaming audio from all your compatible home and mobile devices. It's equipped with four drivers—two 3" woofers and two 0.8" tweeters—and two passive bass radiators that are designed to deliver an enhanced sound experience with a balanced and powerful soundstage. In case that's not enough power, you can pair the Studio 3 with another Harmon Kardon Dual Sound enabled speaker for twice the sound.
