Rated 5 out of 5 by from Clear and powerfull sound Bought this about 2weeks ago. Im really happy with this soundbar. Sub has deep lows, which i love. Like someone said before, it shakes my whole room, so my neighbors love my system as i do.

Rated 5 out of 5 by from AMAZING!!! Bass and sound Iv had the 3.1 for about 3 weeks now and let me tell you there is nothing better on the market in the soundbar system catagory. Literally do not look any further unless you’re upping the game with the 5.1. Get this soundbar and forget the rest it does everything you want. The bass seriously will shake your room and the highs are crisp and seemingly endless. Crank this thing up it’s not gonna destort before your ears say no more I promise.

Rated 5 out of 5 by from Awesome!! Got this 2 weeks ago and I have not turned on my "full fledged" home theater system since! Sure it lacks the refinement of my $$$$$ HT system and isn't as immersive as having 7 physical speakers around me but as far as soundbars go this is awesome - especially the subwoofer. I never expected a subwoofer that came with a soundbar to be able to shake my room. I even had to turn it down a little bit.

Rated 5 out of 5 by from Amazing I finally made my purchase at a local Best Buy and all I got to say about this system is that sound quality is just amazing, that 10inch subwoofer has such amazing bang! Overall this Bar 3.1 is amazing.

Can you fix this very big mistake in future update? Automatically turn off the speaker when there is no signal? This is very annoying when you scrolling in game menu or somewhere. Please set it to real 10 min without signal and not to cca 1 ms.

Asked by: Jojin88
I'd like a solution too. Six months and no updates, nor answers? I want my soundbar to never turn off. Ever.

My product won't connect to the wireless subwoofer, how do I go about syncing them together? There is nothing stated in the guides and manuals

Asked by: willrojazz
Sorry for the inconvenience. Please refer to the steps below, for your information as well, moving forward: 1. Turn on the soundbar and the subwoofer. If the connection is lost, the LED indicator on the subwoofer blinks slowly. 2. Press the CONNECT button on the subwoofer to enter pairing mode. The LED indicator on the subwoofer blinks quickly. 3. Press and hold the DIM DISPLAY button on the remote control for 5 seconds, followed by short press on BASS+, and BASS- button in sequence. Panel display will show “PAIRING”. If pairing succeeds, the LED indicator on the subwoofer lights up, and the soundbar display will show "DONE”. If pairing fails, the indicator on the subwoofer blinks slowly. Lastly, if the pairing fails, repeat the steps above.

Anyone else have volume issues with Fios?  Any button I use on my cable or universal remotes changes the volume based on its last volume input. Never had a problem with COX cable box. Anyone have a fix. Put in tech request a week ago

Asked by: Gsilcox
I am having this exact same issue.  It somehow repeats the last command given to the Bar 3.1 whenever I use the remote for my Fios DVR (Arris VMS1100).  I just got the soundbar yesterday and was happy until I discovered this issue.  If support can't help me, it is definitely a dealbreaker.  Hopefully they helped you out.

Soundbar keeps turning back On after I use my Harmony Ultimate One to turn it off. I have yet to get it to obey all the proper commands/activities from my remote (it keeps flipping to the wrong input, etc). Any help to get these two to get along?

Asked by: abenglish84
Hi! You could double check if the source/s are set to CEC, and is connected to the JBL Bar 3.1 via HDMI, this could be causing problems. Try turning off any CEC on the devices that are connected to the 3.1, and see if that helps. If the issue still persists, wewould like to work with you directly to help you with your issue. Please submit a case request at https://www.jbl.com/support-contact.html and the Customer Service Team will be more than happy to assist you.

When scrolling in menus (games, Netflix etc), a 0.6 s lock-on time is not sufficient to give the user a satisfying experience. Isn't it possible to "stay connected to the source" like any other speaker, without any delay?

Asked by: Andreas92
Please contact Harman Helpdesk about analysis of your issue here. We are not sure we understand the exact problem.
