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

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
