Rated 5 out of 5 by from Why not wireless dual sound produce stereo? I extremely satisfied with the current onyx 3, so I bought the second unit for more dynamic sound. But I realize that the sound output is mono instead of stereo after wireless dual sound connect. Please help !

Rated 5 out of 5 by from Excellent all-round speaker! I had a hard time deciding between the Onyx 3 and some of the Bose speakers just on specs. After hearing them side-by-side at a local shop, the Onyx 3 was excellent for the types of music I listen to! Good clarity and excellent bass response.

Rated 5 out of 5 by from Incredible sound for a great price Incredible sound for a great price. You can listen to Vivaldi and marvel at the purity of the strings or listen to Bruce Springsteen at amazing volume and enjoy the percussive depth and portable – the batteries last five hours!

Rated 5 out of 5 by from Great Sound! Especially With Duel Sound! Purchased 1 day ago after watching videos and reading reviews for wireless Bluetooth speakers in the $200-500 price range. I ended up buying a pair of the Onyx Studio 3's for the Wireless Duel Sound feature and couldnot be happier with my purchase. The sound from one is fantastic but having two side by side the sound is SO much more dynamic! It links very easily and is crystal clear sounding.

I know on the HK Onyx 2 you are able to take the cover off the front of the speaker. Can you do that on the Onyx 3, if so how could I do that without damaging anything?

Asked by: YuCai
Yes, the speaker grill of the ONYX STUDIO 3 is removable by carefully pulling up the cover taking note of how it was attached.

First off I love these speakers, so much so that I got 4 of them and completely stopped using my amp/speaker setup. Would they work with a stereo split into mono cable for input so I can have left and right sound, or will only half the speaker work?

Asked by: Ezikyl
Unfortunately, the ONYX STUDIO 3 does not support stereo either via the Wireless Dual Sound feature or via the setup that you are trying to use. Both speakers would output the same audio at the same time coming from the source.

What is the difference between the Onyx Studio 2 and 3?

Asked by: sundog
The most distinctive difference between the two is the Wireless Dual Sound feature of the ONYX STUDIO 3 that the ONYX STUDIO 2 doesn't have. This feature allows you to wirelessly connect two Harman Kardon Wireless Dual Sound enabled speakers to elevate your music listening experience. Other than that, both have same specifications.

How many can you conect at one time

Asked by: MELVIN
The ONYX STUDIO 3 can only be paired to one Bluetooh source at a time. You can only pair 2 ONYX STUDIO 3's together via Bluetooth with the help of the Wireless Dual Sound feature.

Why is this speaker cost more than the go+play 2016?  What are the differences in sound?

Asked by: Wirelessdj
The ONYX STUDIO 3 has a rated power of 4 x 15W (AC mode) while the GO+ Play has 4 x 25W (AC mode). The GO + PLAY has a bit more bass than the ONYX STUDIO 2. Due to the ONYX STUDIO 3 has 2x passive radiators, it costs more than the GO+ Play.

REALLY like Studio 3...would like to buy 2 for mantel living room. IF we want to connect device via AUX INPUT cable...can we still use 2 speakers? Or...does the AUX in only allow for single speaker?

Asked by: Gumby
You can still use the wireless dual sound feature even if one of the speakers are connected via the AUX connection of the speaker to a source.
