Awesome sound
Great sound from a small bar... Was suprised how good it sounds. Use outside for a bar area just always have to unplug the sub n bring inside as its not weatherproof.

Good sound/bad connectivity
Will not stay connected using hdmi/arc or Bluetooth. Only way to stay connected is to use optical but the optical cable does not stay connected physically to the port. Sound is really good but connectivity could be better.

Amazing sound - Not so amazing software
This little gem sounds amazing! BUT... there is a problem with the software. Once everything is set up, the HEOS app says a new software version is available. When I did the update, the ability to adjust the subwoofer level went away, rendering the adjustability useless and the overall sound mediocre. I had to reset everything from scratch and decline the update and make sure the auto update is turned off. It took me a few reset attempts to figure this out, and unfortunately tech support was of no help. (I'm still waiting for a follow up from them. I love the way this little giant performs acoustically, but Definitive Tech and/or HEOS need to fix the software problems.

Small size, Big sound
I was comparing this to the JBL Bar 9.1. The JBL was out of stock so I went with the 3D mini. I bought this to replace my W Studio. The subwoofer is identical, downfiring 8” with port on bottom. (I prefer the port on the bottom as past subwoofers with front or rear ports have been filled up with junk by my little children. I was surprised at how very little the soundbar was compared to the W Studio. But it gets loud. Easy setup, plugged included hdmi from the ARC on my tv to the eARC port on the soundbar, I used the other hdmi for my 4K blu-ray player which has separate Video HDMI and an HDMI for audio only. I turned on the 3D mini and TV and it worked right away, instantly paired with sub. Setup with the HEOS App was a little painful, wouldn’t set up via Wi-Fi, ended up having to get out a long Ethernet cable to connect to the internet and complete setup. I look forward to connecting to my new TV with eARC and Dolby Atmos. So far I am happy with my purchase, my wife likes how small and unobtrusive it is. After comparing drivers between the JBL and this bar the only difference seems to be 4 upward firing 0.75” speakers, I prefer the 1” tweeters on the 3D mini both have 4 racetrack speakers. I’m not too interested in upward firing speakers as my ceiling is “A” frame style, so the side angled firing racetrack speakers bouncing off the walls seems like a better bet.

How many watts per channel and does it have up firing speakers?
A shopper on Oct 28, 2022
  Thanks for your inquiry. Definitive Technology does not include power output (watts) in the product specifications. The speakers are all front firing but when playing a movie with Dolby Atmos or DTS:X, the Studio 3D Mini offers a natural sound experience. Theater-grade signal processing for the six-driver array makes every movie unforgettable.
