It's much easier to add midrange to an Acme than it is to remove it from an Eden.
Actually, IMO and IME, I disagree, especially if you are talking about the XST line. With the XLT, I guess I would agree.
There is no way (IMO and IME) to get significant and aggressive mid and upper mid projection out into the room (if that's what you want... of course many don't) through that little mid driver versus the top end of a more full range 10 or 12" speaker.
I always giggle at these comments
