As you noticed i haven't jumped in this debate yet. But I've decided to put in my .02 .
Contour SE driver, have you actually sat in a car with a top notch system? I'm not talking about with expensive equipment, but one that has been set up to drop jaws in competitions? There are a couple of Contour drivers here that have such awsome systems they're in magazines. Try sitting in their cars. You will learn that it's not about what the crap you got in your car, but how've you've set them up. You'll be amazed at how well systems can sound if done right. A lot of people actually rather do car audio setups, than do home audio. Mainly because it's a much greater challenge to accomplish such high standards. Believe it or not, these car audio systems will equal those of home audio.
You're talking about a sub that will play down to 20hz... who cares? It's at the point where our ears will barely hear it. Will you be listening to a track that plays nothing but 20hz all day long? Sure it's nice to know a sub has a low frequency extension, but if it's just bass you're looking for, then it's not really music?
Anyways, try going to a car audio competition, and sit inside some of the top cars. I'm sure you won't be blabbing your mouth away. I've been doing car audio for about 6 years now, and a little bit of home audio. Home audio is a whole lot less challenging. It's still fun to do, but just doesn't erupt my volcano. Dude.. try fixing your hemroid problem before typing. You're making yourself an ass. It was misinformation from people like you that made me spend over 5k on my car audio system, when i realized i could've spend less than 1k, and had it sound even better. Dave is one of them that actually gave me a lot of knowledge to make my car one of the best sounding ones on this puny island called Maui.
