B&W Nautilus 800.....where's the bass?


Is it a well known fact that these speakers lack bass? I just bought them used...two years old....and am very dissappointed in the low end. My CDM 9 NT rears have more bass than these. No kidding. Is this a known problem with this speaker, or could there be something wrong? Since the 9's and the 800's are playing at the same time on the same system I do not think there is any need to list the equipment, but I will just in case it matters.
Sunfire Theatre Grand 2 processor ( all speakers are set to large)
Denon 3910 CDP
Adcom 300 by 7 ( 800's are bi amped with four of the channels.....phase is correct)
speaker wire is 14 guage in a very thick outside jacket
Thanks for your help.

Charlie101-You talk about having anything to offer,go back and read your 14 posts as I did and tell us all what positive information you have ever added to any thread.It seems to me you are just here on some kind of mission to attack one,rather to engage in some type of meaningful audio dicussion.FWIW--JMHO Kevin
Kevin,
You're wasting time here and better get going or you'll miss your shift at Wal Mart.
Charlie101,

Your actions speak to your deficits much more than any insult anyone could conjure up to describe you. You treat people like objects, like you treat the subject matter of B&W speakers.

What is wrong with working at Wal Mart BTW? Charlie101 needs to take some Economics 101, not everyone lets mommy and daddy support them instead of getting a job, and there aren't enough jobs in the marketplace for eveyone to be a CEO at Tweeters.

You've gone from insulting speakers to insulting the blue collar working class. Good work, you are truly a spoiled jackass.
B&W's, especially the 800 series are used in many reference systems. People who understand how to drive them know how wonderful these speakers are. Driving 800's with an Adcom is like asking a whale to swim in a small pond. IMHO, the 800's need at least 300 watts a side before they begin to breath properly...they may even leave the water and do a few rollovers!
