Set name: Soundbar System
I just received this bad boy! Blown away I didn’t want to buy subwoofer. This soundbar has a built in subwoofer. I was skeptical. But true I downloaded the JBL One app. Downloaded the software upgrade! It’s as easy as using the Uber app simple. Watched Battleship, Pacific Rim, Godzilla! Best of the best, bestest for $349 it’s daylight robbery. Not paid by JBL yet, you reading this? ... show more

    • Big Speaker sound in a compact unit
Set name: Soundbar System
When it comes to sound I'm pretty much old school. Speakers had to be big, heavy and separate to deliver quality sound. I cannot deny that despite the great reviews I was skeptical that this sound bar could even come close to reproducing a surround sound experience that I am used to with my 7 channel definitive technology setup in my main listening room. That being said, I purchased this to replace a 10 year old Yamaha soundbar with a separate sub woofer that I had hooked up in the bedroom. I am not disappointed. As a matter of fact, I am pleasantly surprised with the sound quality and size of this unit. It measures 4" deep, 2" tall and 37" wide. All mounting hardware is included but I didn't even bother mounting it on the wall. It fit neatly underneath my TV setup. It also included an HDMI cable and a remote. To test out the sound I played the Titanic from its collision with the iceberg. This sound bar handled it flawlessly even at low volume and also handled much quieter scenes with precision. The unit seems to be well-made of quality materials. Easy setup. However, I think it requires the use of an HDMI Arc connection from the TV but It may work with a standard HDMI connection although I can't say for sure. I am thoroughly satisfied with this purchase and would recommend it to others. ... show more

    • Great all-in-one system.
Set name: Soundbar System
Amazing quality sound and very easy to set up. One-touch calibration and the smartphone app will have your system connected to the internet and software updated in about 5 minutes. Built-in subwoofer is excellent and delivers all the thundering bass you’d expect from a satellite system. Makes dialogue clear and proportional to the rest of the audio, movies are easy to hear & understand even with the volume turned down. ... show more

As expected, Dolby Atmos was basically non-existent. The voice quality is not ideal and could be improved, but it's functional. Sound effects are very good. This replaces my Sonos Beam and I'm keeping it.
