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.

I have a older Harman/kardon Woofer speaker but need the connection that goes to the computer.

Asked by: tobnik1
Yes you could actually directly connect the soundbar to the computer using an analog audio cable for the audio signals to be directed to the speaker.

Hello! i just bought this soundbar a few days ago, it is great, but i'm having a very annoying problem when i play music or anything through bluetooth, what happens is that the sound comes late when changing the track, is there a way to fix this?

Asked by: Gtappia
Bluetooth has a natural limitation on the delay to the device. In other words, it takes time for the sound to get from the file to the Bluetooth transmitter, and then into the Bluetooth receiver in the SB 20, before being projected out of the speaker. Some phones or tablets are better at compensating for this than others.

We just bought this product for Christmas, unboxed it, plugged it in, and we can't get hear anything from the speakers and it's connected to the TV.  This Quick Reference Guide is not helpful at all. Please help.

Hi. I have HK SB20 soundbar. How does sound "feedback button"? When I turn it on (I guess from sound), I had to also get sound feedback of pressing other buttons like (HK volume or bass turning up or down), but there is no sound. Tanks

How do I know if Harmon Vol is on or off? There's a button but no indicator... 

Asked by: Ginx
Hi Ginx, Thank you for your question. Harman volume: No more loud commercials or other sudden volume changes and Harman Volume automatically keeps audio changes smooth. If your commercials are too loud when watching TV, then Harman volume is not on.

I've just bought this soundbar - to go with an imminent 4k TV purchase - I see from this comments that it's not 4k compatible (due to HDMI speed) presumably though it can work with 4k TVs via optical or standard audio cables? 

Asked by: Ginx
Hi Ginx, Thank you for your question. The information you have is not correct. Since the SB20 does not have any inputs for external devices and only TV connection, then it does not matter with HDMI speed. It will work with your 4K TV via HDMI, Optical or analog of your choice.

Hello. I have HK SB20. How can I know what level of subwoofer is turning on? There is no display on soundbar or remote. Maybe there is so app, to know on what level is soundbar turned on. Tnk.

Asked by: Atis
Unfortunately, there is no way to see what level the subwoofer is on - there is no OSD feature available for the HK SB20.

I have just bought and installed an SB20, but I can't get the remote control to function. Before you ask, the battery supplied is properly installed in the remote unit. Secondly, what is the "Phase" button for on the back of the sub-woofer?
