I happen to like my SVS which also happens to be the size of a small skyscraper! :-) I like the cylinder design and the engineering reasons for doing it in cylinder form. Hell everyone here always goes on about HSU this and that but did you ever notice when you get in to there line of subs over $1000.00 it goes cylinder? SVS subs do music just fine and dandy. I have no idea how come some people think they don't. Not sure if it matters but the SVS PC-Ultra that I'm running if I'm not mistaken uses a 12" metal woofer.
