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.
baffled
Thumbs up. I'm happy for you. Be careful with the tubes on on your speakers. They will reveal the hiss of tubes if you use them on preamp. This drove me nuts with my Conrad Johnson PV 9. Think about bi amping. You will open up the next door on your journey. Good luck
Bet the room is too small, and the old speakers had a mid-bass bump. Get better amp, and use vinyl for more bass. If your room is small, it is physically impossible to get low bass. The 800's are more accurate than the cdm 9 and won't add bass for effect, so you must get it out of your amp,source, and music.
