i should be getting a tc-3000 in a week or so, ill tell you how that goes. but i would say from what i heard they are a sq oriented company, but the tc-3000 and up and the lms series give you serious spl with quality.
I have a TC3000 12", it's a great SQL subwoofer. Sounds great and gets very loud doing it. They get very loud even in small sealed enclosures. I can't even imagine how loud this beast would be when ported.
im bout to port my 15 in 3.5cf when i get it but i only got around 700 watts.... gonna upgrade the amp when i get the money how many watts are you giving it?
