I currently am living with someone that runs two parts express knockdown flat pack sealed 15 inch boxes which is the exact same door 15 inch set up that I am currently about to do. He is running UM – 15–22 gen ones supposedly the gen 2’s sound better can handle a little bit more power. And is overall a better sub I haven’t heard it, but I love the look of both models. I am in love with the sound coming from the first generation subwoofer along with the Behringer NX 6000 D that we are both running all around is an amazing sub it digs deep it sounds absolutely amazing. It’ll blow your mind on DIY builds it functions amazing you can throw a lot of power at it and they will not blow. They will blow your mind in my opinion. The best bang for the book there is to buy if you run the right DSP settings, which it is a pain in the ass, but you can get them to sound absolutely phenomenal and cranked them to outrageous levels without bottoming out or distortion. They are all around a durable sub and I very much like them. I am super super super impressed. I cannot wait to buy a second one and get them to installed in my boxes and running. I will update this with videos very soon.!!!! ### ⭐⭐⭐⭐⭐ best for the money *by on Reviewed in the United States March 29, 2026* this is the absolute best subwoofer you can get for 120$ if your chasing deep chest felt lows and low end extension. not an spl built driver but it still does get pretty loud too. you won't find a better option from any popular brand for 120$. buy it. absolutely digs the lows in my 29hz tuned box. ### ⭐⭐⭐⭐⭐ The best keept secret!!! *by on Reviewed in the United States March 21, 2026* Very low distortion even at high cliping. Sounds great in the prefab ported skar box. Highly recommended. Very musical bass..Great build quality. Alot more high end then kicker or skar. ## Frequently Bought Together - Dayton Audio UMII12-22 Ultimax II 12" DVC Subwoofer 2 Ohm Per Coil - Facmogu 2PCS 2.2 Inch Square 2-Way Speaker Box Terminal Cup with Banana Plugs, Screw Type Binding Post Subwoofer Box Speaker Terminal Plates for DIY Home Car Stereo - Scosche LOC2SL Line Output Converter with Remote Control Knob - 2CH High/Low RCA Converter Car Audio - Ideal for Subwoofer Amp - Line Level Converter for Car Stereo - Easy Installation - Quality Sound --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/651816966-umii12-22-ultimax-ii-12-dvc-subwoofer-2-ohm-per](https://www.desertcart.jp/products/651816966-umii12-22-ultimax-ii-12-dvc-subwoofer-2-ohm-per) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-06*
