Good small soundbar. I purchased the 2203 model, which is a single piece 2.1 unit with bottom firing powered subwoofer. Its better than expected and more than hoped for. I don't know what you might make of it if upgrading for a television. That may depend on the sound of your television already. But if upgrading for a PC set up and coming from a basic 2.0 system like I was, this soundbar is awesome. And I'm very glad I didn't choose from the plethora of sub $100 computer speakers I was considering. Given my research I can't imagine they'd be as solid as this soundbar.For reference I was upgrad

I have a projector for my entertainment set up, I wanted to get something that made the volume much louder for my room.My room is rather small and this fits perfectly in front of the projector with no issue. It's very simple to connect to your devices using the app. The app on the phone is very simple, it auto turns on the speaker when you open it. It can also be used as a remote. You can use the app to make EQ profiles.Pro's- Great cost, Small sound bar but mighty!- Phone app is very easy to use and install. Quick log in and set up. Phone app can be used as a remote. Great EQ Profile set ups-
very good for the price not gonna lie. my literal only problem with this soundbar is that i wish the bass was a little heavier, but im a bass head so that comes with the game, do not get me wrong the bass is 1000% there. i’m actually impressed. it literally only needed 2 cords to work! i chose to use a AUX cord and plugged it into the back of my monitor (which made me have to do some cable management but that’s normal) the only other cord i had to use was the power cord. other they that flawless setup!!!! very good bluetooth and was easy to connect, also the remote is very nice and has a bass
Well-made product. This soundbar has great sound quality and plenty of connections to fit any need. I purchased this one to connect to my PC, Xbox, and PS5. With the aux connection coming from the monitor, that was all I had to do in order to get great quality sound.The small factor and sleek appearance ties in well to my desk.Set up was easy, just plug and play. The included remote was nice, as well as the app for use. Touch controls on the top of the soundbar were easy enough to access for ease of use.
Buying this for a desk instead of a TV was the best call. I work from home and wanted to replace my traditional office speakers, and this has completely taken over daily duty at my work station. It fits perfectly under my 49 inch Samsung monitor, which is exactly the kind of tight space where a lot of speakers do not work.This was honestly a no brainer for me. I already own several ULTIMEA sound bars, including their bigger models and the powerful new one from their recent Kickstarter, so I knew going in that the brand is reliable. That track record is a big part of why I did not hesitate on t
I wasn’t expecting much from a compact soundbar at this price, but the ULTIMEA Poseidon M20 Pro 2.1ch Soundbar completely exceeded my expectations. Simply put, this thing is incredible bang for the buck. Setup took just a few minutes. I connected it to my TV with the optical cable, powered it on, and immediately noticed how much fuller and clearer everything sounded compared to my TV’s built-in speakers. Dialogue is crisp and easy to understand, even during busy scenes, which has been a huge improvement when watching movies and streaming shows. What really impressed me is the built-in subwoofe
Works great in the mid range and higher frequency, but I was not satisfied with bass.I use it my study at typically low volumes, so an investment in a subwoofer is maybe a long range plan.I suspect all sound bars are the same, and do not provide a full range sound without a subwoofer.This is reason for 3 stars instead of 5. Otherwise, this is a nice unit.
I'm really quite impressed with this sound bar so far. While it does not have response for the lowest lows in many songs, it does most songs justice. It won't rattle the windows, but it does have a little 'punch' and will satisfy the needs of most, as long as you are not looking for Richter Scale registering bass. Volume capability is more than enough. I love bass (the instrument) and this will suffice for most of the music I listen to (Jaco Pastorius, Victor Wooten, Marcus Miller, Bill Dickens, Stanley Clarke, Steve Bailey, Bunny Brunel etc). I can listen in my design studio and not annoy my
