Onyx Studio 3 is rated 4.6 out of 5 by 123.
Rated 5 out of 5 by from Amazing!! For a refurb unit, the sound it produces is amazing and C & C (Crisp and Clear). Design looks simple but high end. Connectivity is a breeze. I use this speaker with my tv and it’s just what i needed. the only drawback is it does not have it’s own remote which is fine with me because i can use the remote of the audio source. At the end of the day, it was a great purchase for me.

Rated 5 out of 5 by from Even better than imagined! I already own a Omni 10 speaker that I love. When I saw the Onyx 3 on sale, I thought why not give it a try. I can't believe your speaker could be improved upon. The Onyx 3 sound is richer and Fuller. The quality of the speaker design and build gives me both a light weight speaker in sturdy package I trust to travel with me.

What are the Stero Options w/ a pair of Onyx Studio 3 speakers? Wired? Wireless? Bluetooth but wired together?

Asked by: Dan Brooks
Hi! Yes, you can connect a pair of Onyx Studio 3 speakers wirelessly. The speaker is capable of connecting using the Dual Wireless Sound feature, all you have to do is long press the Bluetooth button to connect another Onyx Studio 3 for louder sound. Then once connected, open the Harman Controller App to change the mode to Stereo.

And, connecting directly, what cable(s) are needed, and if connecting a pair for last and right stereo, do all speakers (tweeters, etc..) work is each speaker?? It would be really handy if this info was simply available in the guides, quick start and spec

Asked by: Dan Brooks
Hi! You could use an auxiliary cable if you wish to have a wired connection to the Onyx Studio 3. Also, if you have two speakers playing in stereo mode, yes all the speakers will work. The Quick Start Guide for the Onyx Studio 3 speaker is available on this link: https://www.harmankardon.com/top-rated-speakers/ONYX+STUDIO+3.html

Hey. I have a simple question: could my HK be damaged by trying to charge it with 19.5V and 6A charger? I lost my original charger and tried to charge it with PC charger, but seems like it is not charged.
