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.

This is baffled....the Audiogoner formerly known as [email protected]. I started this thread eight months ago when I was just getting my feet wet in this hobby. I am happy to say that I found SOME of the bass when I replaced my Adcom amp with Classe. I found ALL of the 800's bass when I replaced my Denon 3910 with a Musical Fidelity Tri Vista tube CDP. All cables have also been replaced. I have an Aesthetix Calypso on the way. These speakers continue to amaze me as I upgrade my digital front end. No complaints....no worries......just good music.
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.
