HK SB20 is rated 4.1 out of 5 by 16.
Rated 5 out of 5 by from Best Soundbar I've ever owned Recently, I replaced my old speakers with this soundbar. And I had no regrets. This sound bar is simply exceptional and really impressive sounding. It played almost all genres of songs really good. It's warm bass, powerful mids, and crystal clear highs handles the job easily. When I watch HD concerts I can't help but pump the volume up because the sound is just so real and immersive; it's like being there in the concert hall. And with the movies? It's bass is really tight and punchy... I can say for myself, as a cinema goer, that the sound coming from this speakers is close to that in movie theatres and sometimes I think it is even better; clear dialogue, powerful explosions, I can even pinpoint where the tiny sounds like bullets ricocheting are. Although, it lacks simple features like indicators for tuning the bass with the remote.

Rated 5 out of 5 by from I need instructions for the wall mount Everything is great. Is there anything anywhere that illustrates mounting the sound bar?
Date published: 2018-11-10
Rated 3 out of 5 by from Poor documentation I think the sound is mostly fine except, though there's a lot of boom from the subwoofer, I'm not hearing much between that and the mid range. We were able to set this up quickly, but we have no idea how this system is intended to interact with the TV. There is no such thing as a user guide, either in the package or online. There is only a quick setup guide that has almost zero instructions, just lists of inputs and button names. The setup guide has eight pages, but 65% of that is taken to repeat the labels and a list of specs in 19 languages. There are features with no explanation, such as Harmon Sound. When would you enable or disable Surround Sound? What do the different colors of button lights mean? What are the pros and cons of the connection options? Also I don't like having the buttons on the top of the soundbar: You have to walk over to it to see which buttons are lit, and what color they are. The remote is small and easy to lose, and it's dark: Even the button indicators are dark, so you need to turn on a light to find the button you need.

Does the unit have the capability of being used with another remote? AKA a universal remote.

Asked by: JMendoza
Just to be clear, this sounds bar does not "Learn" other TV remote codes for basic control. For example samsung TV, power on command and Volume up command. Please let me know.

Can I connect SB20 soundbar to Adapt+ & use it to sync music with my Omni 20+ speakers.

Asked by: harshal
Great question! Yes, you can connect your HK SB20 to your Adapt Plus via Bluetooth, optical, or auxiliary then set it up on the HK Controller App. Once you have your Adapt Plus set up on the app, you should be able to stream the same music across your Omni speakers and your soundbar. If you need help with the set up, you can reach us through here: https://www.harmankardon.com/support-contact.html

We'd suggest to get an SB with a separate subwoofer to get more bass.
