can I get some opinions - bass on magnepan mg20.1

can another audiogoner give me experienced opinions of the bass on the 20.1's - I just got a new pair and have been breaking them in, but I have no bottom end to speak of. It sounds like the woofers are 5-6db behind (lower output)the midrange and tweeter ribbons. I have tried many room positions and equipment changes no drastic changes result in the bottom end. equipment is a BAT pre;MC501's; and a Marantz SA7S1 CD. Help I'm going nuts - you should not have to try hard to like and listen to your system.

Thanks for your response. Greg.
