    • Highly underrated

Review Image by Bigdaddydeas Bigdaddydeas
These are some serious 12s. I also have the monolith 18s. You won't be disappointed. I won't name bash on here but I can assure you I've owned very very well known brands but those brands are a serious let down after getting these bad boys . All brands have to start from the bottom. They offer product at a discounted rate . Then they let the product speak for itself. The monolith subs and Harmony Audio amps in my opinion will be the next big name in car audio. It's just a matter of time. Im sure after this happens the prices will definitely go up. I would get them now while pricing is low. ... show more

    • There awesome subs well worth the 300$
Size: 1 Ohm Style: Single Pack
I wrote a review a few months ago when I first got one so now is the 6 month update. I love these bad boys!!! They def hit hard has hell in every box I’ve put em in. I’m doing a custom bench in back of my f150 with 4 of these and two hifonics colusses 6000 watt amps. I’m jus waiting on my other sub now and it’s going in. I can’t wait!!! But def worth the money compared to sundown and dc audio. It was a toss up because I heard Skar is good to but I went with these and I’m glad I did. Very sturdy construction good motor nice stiff sub but not to stiff and spider is big so it flexes more than the others. ... show more

I bought the monolith 12 and the box that goes with it it sounded good while it worked. But today I was moving the sub and box out of my car. I picked up the box and the basket broke. I removed the subwoofer and this is the damage that was revealed. The company was helpful while in the warranty process and ensured it was a painless experience. ... show more
