Features

  • Wireless Adapter for Up to Two Subwoofers: SUB10 includes a wireless subwoofer adapter for flexible low-frequency signal transmission with under 20 ms low latency. The adapter can pair with up to two SUB10 units, allowing single-sub or dual-sub placement without running long subwoofer signal cables across the room. This helps simplify installation for home theater, HiFi, soundbar, and bookshelf speaker systems. Each subwoofer still requires AC power.
  • 550W Peak Power and 20Hz Low Frequency: The 10-inch high-excursion driver with Class-D power delivers up to 550W peak output and extends low-frequency response down to 20Hz for dedicated bass in home theater, HiFi, music, and gaming setups.
  • App Bass Control with 1 Phase Adjustment: Use the ULTIMEA App to adjust volume, low-pass crossover, 6-band parametric EQ, and phase from 0 to 180 in precise 1 steps for detailed bass tuning. The rear-panel phase switch offers 0 or 180 settings for quick manual adjustment, helping the subwoofer blend seamlessly with your speakers.
  • 30-180Hz Low-Pass Control: SUB10 lets you adjust the low-pass crossover from 30Hz to 180Hz, allowing the subwoofer to blend with different main speakers and room setups. Set a lower crossover point for larger speakers, or a higher crossover point for smaller speakers that need more low-frequency support.
  • Professional Inputs and Outputs: SUB10 supports multiple connection options, including Line/LFE input, RCA input/output, XLR balanced input/output, and speaker-level input. It works with compatible AV receivers, amplifiers, soundbars, HiFi systems, bookshelf speaker setups, and professional audio devices.
  • Engineered Cabinet and Complete Accessories: The engineered wood cabinet and removable protective grille support stable low-frequency playback while protecting the 10" driver. The package includes the subwoofer, protective grille, power cable, RCA cable, 3.5mm to RCA cable, wireless adapter, dongle cables, USB power cable, and user manual.

Description

Send subwoofer signal wirelessly through the included adapter. Each subwoofer needs AC power. Adjust volume, low pass, 6-band PEQ, and 0°–180° phase through the ULTIMEA App. App-based phase control adjusts from 0° to 180° in precise 1° steps. The 10" driver with Class-D power delivers 550W peak output and extends down to 20Hz. Supports Line/LFE, RCA I/O, XLR I/O, and speaker-level input for audio systems. Adjust the low-pass crossover from 30Hz to 180Hz to match your main speakers. Engineered cone and robust driver structure improve low-frequency control for tighter, cleaner bass. The removable grille helps protect the 10" driver from dust and accidental contact. Add dedicated low-frequency output to AV receivers, soundbars, and home theater systems. Connect SUB10 to ULTIMEA BS-3 bookshelf speakers or HiFi systems for dedicated low-frequency output. Enhance your PC audio setup, soundbars, or speakers with SUB10 via RCA or wireless adapter. Does this subwoofer need to be plugged into power? Yes. SUB10 is an active powered subwoofer and requires AC power. The wireless adapter only transmits the audio signal wirelessly; it does not power the subwoofer. Is this subwoofer fully wireless? No. The included wireless subwoofer adapter sends the audio signal wirelessly, but the SUB10 still needs to be connected to AC power. What devices can I connect this subwoofer to? SUB10 works with compatible AV receivers, amplifiers, soundbars, HiFi systems, and powered bookshelf speakers through Line/LFE, RCA, XLR, wireless adapter, or speaker-level input. Can one wireless adapter connect two subwoofers? Yes. One wireless subwoofer adapter can pair with up to two SUB10 units for single-sub or dual-sub placement. Each subwoofer still requires AC power. What can I adjust in the ULTIMEA App? The ULTIMEA App lets you adjust volume, low-pass crossover, 6-band parametric EQ, and 0°–180° phase in precise 1° steps for detailed bass tuning. Our founding team began as passionate audio-visual engineers. Seeing movie and music lovers turn away from high-end audio—deterred by complexity, outdated design, and high costs—we set out to change that. Ultimea reinvents home theater with breakthrough acoustic engineering, modern design, and cost innovations, making cinema-grade sound accessible to all. Started in Seattle and now trusted in 100+ regions, Ultimea is redefining home theater.

    • This 10 inch sub is a beast!
Size: 10 inches
Just got this delivered today and OMG! It's WAY bigger than I thought it would be. Yes I read the dimensions but dang. It took less than 5 minutes to set up and start using it. I have the BS-3's already in use so connecting the sub was just plug and play for me using the sub out. Brought the app and connected to it right away and bam bam boom! Done. And the boom boom of the bass hit me like a truck. Wow! Just wow. I am so happy with my purchase, more than happy. Thank Ultimea for creating an excellent sub and bookshelf speakers that I could afford. Now to hunt down and destroy the little critter that crawled out of the Amazon box the sub was shipped in. LOL. ... show more

    • Real bass without cable hassles
Size: 10 inches
If you are not familiar with Amazon Vine, it is basically Amazon trading free* products for honest reviews. I do my best to make my reviews honest, real and value-oriented as if I had paid for each item I receive. * These items are not totally free as Vine members pay income tax on the items they receive. I only mention this because we Viners do have some skin in the game for each item we order. Why I ordered this item: My home theater sub died a few months back and I've just been using the bass from my soundbar since. It's not cutting it for movies so I wanted something dedicated that could shake the room. Likes: * This thing hits low. Like stupid awesome low. Explosions in movies have that chest thump I was missing. * I ran the wireless adapter with no cable across the living room floor and it kept the bass thumping steady the whole time. * The app lets you mess with the crossover and EQ from the couch. I spent a good twenty minutes just nudging the phase setting back and forth until it stopped sounding funky with my front speakers. * The cabinet feels dense and doesn't buzz or rattle even when I crank it. * It comes with basically every cable you could need. RCA, XLR, the little 3.5mm adapter, all of it's in the box. No likes: * The app is a little screwy on first setup. It dropped connection twice before it found the sub and I had to restart my phone's bluetooth. * Still needs its own power outlet even with the wireless adapter. * At max volume I did get a little rattle from the grille, had to pop it off. Would I pay full price for this product: Yes Final thoughts: This is a real subwoofer for people who want actual bass, not just a box that hums along with the soundbar. Not having to fish a cable across the room to hook it up is the biggest win here. ... show more

    • Surprisingly Versatile And Feature Packed With Mostly Good Sound
Size: 10 inches
Okay so let's just get size out of the way real quick, this thing is big and you're going to need some space. Great, now let's talk about it. So it is big and heavy but in a really sturdy and quality feeling way. It feels very polished and well put together. You also have multiple options for connectivity, both in and out. It comes with a wireless adaptor to be able to use it wirelessly with other sound systems and doesn't lock you in to the Ultimea ecosystem which is really refreshing. And the wireless actually works surprisingly well with no dropouts or lag. I even tested it by going directly from my TV out to the wireless adapter over to the sub and it sounds good. You have plenty of control directly on the sub itself as well as through the app, which is nice. Now, the sound... It's mostly good, it's very clean and punchy through most of it's range but there is one small spot where it can get a little buzzy unless you turn it down. I don't know the exact frequency but it's in there. That being said, at normal volume (still quite loud) it sounds great. It's not the cheapest subwoofer available but for the features you get and the punch this thing delivers I would consider it quite good value. Setup is going to vary based on how you decide to go about it ranging from really quick plug and play with the wireless to a full on wired system going through as many devices as you have crammed into your system. I have tested in a more open theater room and a closed off living room and it delivers equally well, just make sure you have the volume of space needed for this thing. ... show more

    • A Subwoofer for People Who Actually Want to Feel the Bass
Size: 10 inches
I already have experience with ULTIMEA audio products, and one thing I've appreciated about the brand is how much attention it gives to sound customization. This 10-inch powered subwoofer is an interesting addition for anyone who wants more low-frequency sound than smaller speakers can provide. What stands out to me is the amount of control available. The app-based equalizer, bass adjustments, and phase settings give you more flexibility than a subwoofer with nothing but a basic volume knob. I also appreciate the different connection options, including RCA/LFE and speaker-level inputs, because that makes it easier to incorporate into different audio setups. The 10-inch driver is a substantial size for a home audio system, and the advertised low-frequency range suggests that this is intended for more than just adding a little extra thump. One thing I always consider with subwoofers is placement. Where you put one in a room can make a noticeable difference in how the bass sounds, so it's worth experimenting with positioning and settings. I like that this offers detailed adjustment options rather than expecting everyone to use the same bass configuration. ... show more

    • Incredible Bass & Easy App Control, But Check System Compatibility!
Size: 10 inches
Review Image by Quibb
I received this ULTIMEA 10" Powered Subwoofer and was immediately impressed. The quality is great, it looks and functions really well. I am not a tech guy when it comes to speakers, they either sound amazing or they don’t. The rest is just kind of Chinese to me. The included wireless adapter was a game-changer. It allowed me to place the subwoofer in the spot of my choosing without running cables. The Bluetooth hookup was fast and effortless. Instead of twisting knobs on the unit, that I have no idea what they do, I could use the app to control the bass level and adjust the equalizer settings directly from my phone. It has a massive amount of punch. It’s very loud and very rich sounding, It fills the room with deep, rumbling bass that makes watching movies or listening to music sound amazing. It features Bluetooth as well as multiple traditional plug-in options, meaning it can connect to just about anything from a standard TV setup to a high-end receiver. With that being said, if you currently have an ultimea system and are just wanting to upgrade the bass speaker it came with be aware, my system was not compatible with this speaker. I have an Ultimea A50. If you are into music this definitely has value for your dollar. It has a max of 550W of power. The grill comes off if you prefer that look. One thing to note, the driver is 10in, not the unit, that may be common knowledge to most but I was surprised to see the actual unit was big, really big. 17’ high, 12’ wide and 18’ deep big. With that being said, If you want deep, bass and want the convenience of app controls and wireless placement, this subwoofer is incredibly capable. It would definitely upgrade your home audio experience. I knocked it down a star simply because I think you should be able to upgrade an ultimea system, with high end ultimea pieces. Other than that I would recommended this product. ... show more

    • ULTIMEA has made a BOOMing entrance to the powered subwoofer market!

I currently have two Ultimea Dolby Atmos surround sound systems and recently acquired a pair of their BS-3 powered bookshelf speakers as well. All have been "home runs", hitting well beyond their price point. I was excited to see Ultimea also enter the powered subwoofer market. Upon opening the sub, it appears Ultimea has thought of everything. Every cable/connector that could possibly be needed is included inside the box. Instructions are straightforward. One can stream the signal to the Ultimea wirelessly, or do a direct input with the included cables. For our application, we hooked them to a pair of powered bookshelf speakers that sounded great but were severely lacking in the bass category. The music is now rounded out and sounds absolutely wonderful, marveling that of my component system, yet was only a fraction of the price. Listening to music and movies now isn't just a process now... it's an experience... being able to feel the music instead of just hearing it. The build quality is phenomenal. It has a real-wood enclosure that is very sturdy, and a removable grill. Even the binding posts (for speaker level input) are incredibly high quality. It's almost a shame to have this tucked away in the corner. The free Ultimea app makes adjusting bass volume, low pass filter, and EQ incredibly easy. If you don't want to download the app you can also adjust bass volume(/gain) and low pass filter with the controls on the back of the sub. Ultimea has done it again and I can't wait to see what their future product line-up has in store. ... show more

If you want to add some serious, room-shaking rumble to movie night or music sessions without running long cables across the floor, this 10-inch powered sub from ULTIMEA hits the spot. The wireless adapter is easily the coolest feature here you can tuck the sub away in whichever corner sounds best without worrying about tripping over an audio cable snaking back to your receiver. The low-end response has plenty of punch and weight, effortlessly filling the room with that deep, chest-thumping bass you feel during action scenes while staying tight and clean for casual listening. The app control is super convenient, too. Instead of crawling around on the floor behind the couch to twist knobs on the backplate, you can just sit back with your phone and dial in the volume, phase, and crossover until everything blends seamlessly with your main speakers. It’s packed with input options whether you're hooking it up to a home theater AVR, a vintage stereo amp, or an active speaker setup making integration completely painless. The clean, modern cabinet looks sharp sitting out in the living room without being an eyesore. If you’re looking to bring movie theater energy home and want the freedom of wireless placement combined with quick app tuning, this sub delivers awesome performance and convenience. ... show more

    • This 10" subwoofer is a monster. Awesome bass response.
Size: 10 inches
Review Image by Gautama
I got the 10" subwoofer for my home stereo system and am very happy with it. It was super easy to install. I have (2) Ultimea bookshelf speakers that I use as front speakers and the subwoofer plugged right in to the back of one of the speakers with the provided speaker wire that came with the subwoofer. The 10" subwoofer is rated at 550 watts and is more than enough for my 12'x20' room. I can't even imagine what the 12" subwoofer would do at the rated 900 watts. I paid $300 a few weeks ago and now the price came down to $240, so it is now an even better deal. ... show more
