UMII18-22 Ultimax II 18" DVC Subwoofer 2 Ohm Per Coil

OK so I am loving this subwoofer. 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.!!!!

Great sounding woofer. I went with the Parts Express recommend sealed enclosure and paired it with the Dayton SPA500 amplifier. One of the keys to this woofer in my opinion is to let it break in properly. It was a little weak the first few of days of play but it definitely woke up after the break in period! Definitely a good value if are into building your own speakers.

The most powerful 8 inch sub i own and wow the xmax/excursion is crazy i built a vented box with the f3 tuned to 29 insted of the 33 AND IT RIPSSSS!!!

Why did you pick this product vs others?: Great price. Paired 2 with the Marty Cubes and nx6000D for a home theatre setup. So far I am very impressed. Sound quality is amazing digs deep for without being too loud. These subs round out my theatre setup and does wonders for immersion from bass effects. Build quality: Very hefty speakers with a durable cone. Value for money: Can't beat the price for the size, material, and quality.

Subwoofer was of good quality and after break in I installed it in my box and it has been performing well.

I used this sub to replace an existing 15 in an existing enclosure for my home theater, I wasn't expecting much difference but it was a huge difference! Low base and mid base improvements. I'm using a folded horn enclosure and an external QSD 1,600 watt amp.

I rarely write reviews but I feel I have to for this sub. It's not even broken in and I am amazed at the sound quality and output of this sub! I'm running it at 1ohm on an 800.1 Taramps in a 1.13 cu ft sealed box and this thing sounds AMAZING!!!! Just buy it! You will not be disappointed!!! Super low and clear bass 😁

In the correct ported box and fed enough power, this thing will impress.
