HK SB20 is rated 3.8 out of 5 by 51.
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 2 out of 5 by from Keine ordentliche Bedienungsanleitung vorhanden - schneller Aufbau - Sound nicht wirklich wie erhofft (kann aber auch an schlechter Positionierung im Raum liegen - allerdings gibt es hierzu auch keinerlei Informationen) - keine ordentliche Bedienungsanleitung --> ich weiß nicht an was es letztendlich wirklich liegt, dass der Klang nicht optimal ist - welche Einstellungsmöglichkeiten bietet die SB20 denn? - Die Tasten auf der Fernbedienung als auch auf der Anlage sind nicht selbsterklärend - optisch macht sie ansonsten einen sehr guten Eindruck - geringe Bauform --> überall anzubringen / aufzustellen - Bluetooth Verbindung hat problemlos funktioniert - Ebenso hat die Anlage sich auch automatisch mit dem Subwoofer verbunden

Rated 5 out of 5 by from Améliore nettement le son du téléviseur Très agréablement surprise par cette barre de son qui est livré avec un caisson de basse et une télécommande ultra compacte. Elle permet d'améliorer nettement le son de l'écran, elle donne la sensation d'immersion en particulier pour les films d action, dont on est fan à la maison. Le son puissant elle est compatible Bluetooth pour connecter la tablette ou le smartphone. Très facile d'utilisation elle est doté d'une sortie HDMI et d'un port USB. Le seul reproche que je peux lui faire c'est que je la trouve trop longue elle est posé sur mon meuble TV et dépasse de plusieurs centimètres

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.

No, it is not possible to connect the Citation rear speakers to a SB20. The Citation rear speakers require a Citation Bar.

Hej! (SB20) - Är denna produkt redo att kopplas in direkt och köra eller behöver man komplettera med fjärrkontroll och förstärkare? - Hur mäter denna kombo sig mot er SB26 paket? Hälsningar Jonte

Asked by: Jonte90
Tack för ditt intresse av våra produkter. Du behöver inte någonting annat till en SB 20 utan det är bara att koppla in den. Det följer med fjärrkontroll, subwoofer och andra kablar som krävs för att koppla in den i en TV eller bara användas för musik via Bluetooth. Skillnaden på en SB 20 och en SB 26 är att en SB 20 är lite starkare i antal Watt den genererar. Däremot har en SB 26 två HDMI IN portar i sig där du kan koppla in andra enheter. En SB 20 har endast en HDMI OUT och du måste därför koppla in övriga enheter i din TV.

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

What's the best for a perfect sound? HDMI or optical for a 4K sony? Sincerely and specifically, please. Bluntly. Thanx.

Asked by: Antimengar
I don't think it will support HDMI for 4K TV. I use optical with my Sony Bravia 4K TV. Sound is great with optical even while watching 4K movies.
