Has anyone heard one of these yet? I have read some reviews and all have been good so far. I am looking maybe to get on of these subs. Especially for the price. I have had JL, Diamond, Memphis, Image IDMax as well as a few others. Needless to say I have been around the block with some subs lol. Any input would be greatly appreciated. By the way, this sub would be running on my Cadance amp.
