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.

Yea they are amp picky adcom don't have the best bass power also the right cables are important it's not thickness but the cable itself. I learned they the hard way also copper is not just copper. Maybe see if you can borrow some different cables and innerconnects. They are a tuff speaker to drive. Overall B$W have skued bass and treble some, bass light some and some punchy, but in there defence once set up right they are not to bad and sound better than alot of speakers. Also make sure they have enought breething room if you have them tl close or to far frm a wall you will loose the bass image.

When you stand at the back of the room do you hear more bass?
My guess is your amp. 300 adcom watts may not be enought B&W suck power! You could try bi amping one speaker off your amp or the other just run the bass like sugested above. Also make sure all your innerconnects are tight.

One thing to remember is 2 10" woofers may not make as much bass as 2 8" woofers. Nore should it, it should have the same bass, whatever the original recording has. Also if you are not biwireing do you have the posts jumpered?
