this article / post, really opened my eyes.... er... my ears ;-) to the whole scoop about mid-bass. http://www.the12volt.com/installbay/forum_posts.asp~TID~100789~PN~1~TPN~1 As I had said before, about my super system from back in the day, the only part that never really cut it, was the mid-bass region, even though I had a pair of very nice 7" mid-bass speakers, a dedicated amp, and was sending them a nice, pure, mid-bass signal, via and electronic X-over. This article REALLY answered a lot of questions for me, and because of it, I intend to steer clear of that same path, this time around (20 years later). Peace, Fish
