Review: Amazing subwoofer will blow your mind. buy it. buy it. buy it! do not hesitate!!!!!! - 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.!!!!
