Ultimea Preseidon D80 Boom
I purchased this sound bar about 2 to 3 weeks ago... I'm extremely satisfied and blown away by how great they sound. I'm definitely part of the family now because I will be purchasing more.

Buena en general
En general un 10, pero al menos mi unidad tiene un grave fallo, el sonido usando bluetooth es nefasto, he probado varios móviles con el mismo resultado, una pena

Poseidon D80 the best option for budget
I recently purchased the Poseidon D80, and I must say, it's been a game-changer for my entertainment experience at home. The D80 delivers exceptional audio quality, with Dolby Atmos sound reproduction with a wide and immersive soundstage, audio is crisp and clear, with no muddiness or distortion, and the sound effects and dialogue are perfectly captured. Atmos sound is truly immersive, with sound waves that seem to come from all around.
This is an absolute masterpiece. The quality is exceptional, and the build quality is superb, and the price is on budget.

The app makes all the difference
In a 25x15 foot room this system is more than enough, you feel like your part of the movie, the app puts it over the top your able to fine tune it for whatever you like watching. Had an older setup with a 10 in subwoofer can't tell the difference. I would not hard mount any speakers until you have spent some time with it

Just Buy It
I bought this a month and a half ago and I’m genuinely impressed. I upgraded from a 2 year old Philips soundbar with wireless rear speakers and the rear speakers popped and crackled so much I couldn’t focus. This Ultimea 7.1 is exactly what I was looking for. These speakers are crystal clear.
The packaging was great and I was pleased to find that all of the speakers came with a wall mount.
I mainly keep the speakers in movie mode, though when I play video games I change it to game mode, same with music. There is a noticeable change in what comes through the speakers when you change modes.
I have a fairly large and open living room and I typically keep the volume at 10, which is more than enough. I haven’t seen how loud it gets, but even at 5 it’s easy to hear and understand.
Here’s the summary:
The sound quality is great.
The build quality is great.
The packaging is great.
The connectivity is great.
The app is great.
The bass is punchy.
The whole system is LOUD.
I’d recommend this Ultimea 7.1 to anybody.
