i purchased a mm120 sub at a really good price a while back and im looking to get a box since i dont have the time to make my own. the one i am looking at is here: http://cgi.ebay.com/aw-cgi/eBayISAPI...em=1290265098. will this make the sub sound alright? im no expert at dimensions and whatnot for a sub which is why i came here. if that box doesnt work, is there one you could recommend?
