If your looking for some good quality hi's with exceptional midbass research the image dynamics chameleons, they have to have one of he loudest and cleanest mid bass's i have ever heard.
I know these arent on the list, but they are excellent components, and they are just a little more pricey than the Bostons. I think i may be investing in a pair shortly. http://www.mbquart.com/en/produkte/car/qline/produkt.php?nr=q_216 ......I am kinda shocked no one mentioned MB Quart!
