I was wondering what you guys thought about these? I am intrested in them since there only 200 bucks lol. Are they worth it? Or no, I mide as well just go with the 3000's or nothing from them? And another quick question..not only with TC subs but with other subs as well. If all of the subs make the same power..10", 12" and 15"..why does one spend more for a 15 rather then a 10 if they make the same power?
