Amazing sound at amazing cost 😎
I’ve been using the Skywave X70 Soundbar for a little while now, and it has completely transformed my home entertainment setup. The sound quality is rich, crisp, and surprisingly powerful for its size. Dialogue comes through clearly, bass feels full without being overwhelming, and the overall balance is excellent whether I’m watching movies, gaming, or listening to music.Setup was quick and effortless, and the connectivity options make it super convenient to switch between devices. The design is sleek and modern, blending perfectly with my living room. I also appreciate how intuitive the controls are — it’s one of those products that just works exactly the way you want it to.If you’re looking for a soundbar that delivers impressive audio performance at a great value, the Skywave X70 is a fantastic choice. Highly recommended! You will never regret it.

Surprising Quality and Great Sound!
Was pleasantly surprised with how well the unit was packed. Everything was wrapped and in a foam comparent in the box. The main soundbar assembles from three pieces, and the connections are solid! The app was easy to dowload and install, and all of the speakers are auto-paired to the soundbar. Surround sounds great!! Definitely happy with the purchase; Ultimea makes a quality product at a reasonable price. I bought a swt of Sanus stands separetely to mount the surround speakers to and they work perfectly together.

Get it!
Amazing!!!! True surround sound. The sub is incredible. The X50 elevated my home. My walls and floor and couch vibrate with awesomeness. Im playing all the movies!!!! THANK YOU!! I used AI to compare specs against other systems and this has THE MOST BANG FOR YOUR BUCK against known name brands. Press YES and order it! Let the software update before you judge the system. Trust me!! The soundbar feels “light” but the quality is in the speakers. Don’t let the weight fool you. The sub is exceptional quality and solid/heavy. The wireless speakers are great and the app is amazing for adjustments. Im super happy! Setup was plug and play for me. All paired without issues. THANKS!!

Warning will shake your house
This sound bar bangs!!! I’ve amazed all my friend and family with how loud and hard this bar and sub hit. Connects to all devices and can change back and forth easily . App is easy to use and set up and you can customize your sound to your liking! Was well worth the price ! Also great set up, not many wires , this was the best setup for partial surround sound without the many wires hassle. Fits on the floating shelf I got perfectly. Functions above my expectations , sounds amazing and will shake your house .

Great entry for the Dolby atmos home experience 10/10 recommend
I’m coming from a 2.1.0 LG sound bar roughly 7 years old, I added a 5.2.0 book shelf to the rear to act as rear speakers s couple years ago and it worked flawlessly. So technically, it was a 7.3.0 set up, and it did the job for years, but lately I’ve been wanting to add some more immersion to my TV/ movie time with my lady. But also, didn’t want to spend $1500 – $4000, just to see if we’d like the extra boom and surround sound like other Dolby atmos surround sound systems. I’ve seen a few videos about this brand, I was already convinced to purchase after viewing the review videos on YouTube (specific video YT: B the Installer), luckily for me this was on sale for Prime day so it was a no brainer for me!To start, the set up was a breeze, rear speakers connected almost instantly for me with a solid white light, the cable is a decent length so you can stretch it pretty far, the only difficulty is just making a sure the rear speakers are leveled to each other, where you want them and an ideal location for the massive 10” subwoofer. The bass rumbles so good it shakes and vibrates our bed and walls lol, it all really makes a difference in specific locations depending on the configuration and acoustics of your room. Note in the attached video I have a an additional set of rear speakers that are 5.2.0 working in harmony with the ULTIMEA rear speakers, I must say the ULTIMEA rear speakers with the top firing speakers really changed how my rear bookshelf speakers sounded in a very positive manner, the ULTIMEA Skywave X70 all around added a unique immersion you only get to experience in an IMAX theatre. So I’d say with my rear bookshelf speaker it’s now a 12.3.4 setup with complete 360 surround sound. The volume gets pretty loud(see the attached video), it was only at a 12 volume (bass level set to +3 upfiring speakers set to +1 surround set to +3 for the attached video).The functionality of the system is very user friendly it would be a difficult task to make this even remotely difficult to use. The best part is the price of the system, even when it’s not on sale for $999 this would be a great entry level into Dolby atmos scene or a True 360 surround sound home experience. Only reason for a 4 star instead of 5 my left front speaker had a small dent on top of the topfiring speaker screen, I was really shocked considering how well the packing was, there was no wiggle room for anything in there it was top notch, so I’m assuming they didn’t such a good job at quality control and sent this one to me with a slight dent on the top front top firing speakers for the main bar, it’s not noticeable only because it facing upwards rather directly facing me, other than extremely satisfied with my purchase! 10/10 recommend build quality feels like top notch quality materials, certainly didn’t feel cheap.

Amazing Soundbar
This setup is awesome. Super user friendly as it comes synced from the factory so you literally just plug and play. Sound quality is amazing. I think its false advertising to call it a .4 channel up firing for the atmosphere as true atmosphere is actually speakers mounted in the ceiling. It is super loud, I can’t turn it up more than halfway without the wife going crazy. Its hefty weight too it and feels real quality made. The subwoofer looks absolutley stunning and is super loud for being an 8 inch. It rattles my entire couch and gets the wife cranky. I really only wish that I would have shelled out the money for the 10 inch sub and got the x70.

get that off the table
really good wide screen acting like a external monitor for work.. scotched that straightaway, such a waste.screen properly mounted on uprights and sound bar placed beneath on the table. Looks great, sounds spectacular.configures easily enough and changing formats i.e. sports,music, cinema straightforward.
