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.

Avent91, The amps are Chord Electronics SPM6000 monoblocks. 750wats/speaker. Cables are Transparent reference XL, the current version.
Just received my Classe 700 W mono block amps. Sincere thanks to those who suggested I lose the Adcom amp. You were all right on the money. These 800's have so much bass now I cannot believe an amp change could make such a difference. Mids and highs dramatically improved as well. As a new guy I just learned a valuable lesson about watts AND current. I even dragged out my 25 yr old Cerwin Vegas from the garage system and tried them on the new amps. Seemed like a harmless experiment at the time. Now I am shopping for a new amp for the garage! Thanks to all who responded.
ahcjmh1@......now sit back, put yr feet up and close yr eyes and just listen to the N800 subwoofer and wide wide soundstage......
I am well known in the audio world for many years. I used 802 Nautilus speakers for more than 6 years and now I use 800 Nautilus speakers. I modified some parts of the 802's and used rubber absorbers. Because by using these absorbers the middle and high freq. will be less harsh and the low will be more tight. What equipment you put to you speakers will come out of your speakers. When you listen to your system you hear to every part of your system and of course your room. Every part has his own property. That means when you use more different brands you can use more properties. The sound you like is 100% personal. So you have to look for the sound you like most. When you use power amplifiers of less power, you will get less bass and a less realistic sound of low freq. When you have a big room you need more power to get a full sound in your room. Oh yes the 800 needs power to get a good and realistic sound in the low freq. But when you use the right equipment it can do things only a few speakers can do. The focus of this speaker is of a level I never heard before. When you play accoustic music with a few instruments it is very intimate. You can give every player a hand when you are listening. When you do would play this music by a Wilson or the Vocal speakers you will miss this feeling. It is less intimate and it does not reach you soul inside. It is a 100% fact that Nautilus speakers dominate the market. I don't like the way the way th advertise. But the sell over 50& of the whole highendmarket. That means the rest all together sell less. It is also a fact that this speaker is used in many studio's. When a person says that the don't he has to come with facts before he makes this anouncements. Some people call this speaker lean, but I call it neutral. It is less lean than Avalon speakers are, because the bass is muce more warm and sounds rounder. With my system it sounds very musical, detailed, fast, a lot of depth, a focus to die for, a wide stage and very intimidate

My system: 800 Nautilus, Meridian 800 V4 ( model 2005), Musical Fidelity Nu-Vista 300 power, Nordost Valhalla speaker cable, 2 Valhalla powercables, 1 MIT AC-1 Oracle powercable, Acapella rca with WBT Nextgen, feet of silence, KE Powersource ( conditioner )

I have listen many times to the 800's with Mark Levenson and Classe, but I never liked the sound of it. It never touched my soul, and that is where music is all about. My hobby first is music and after that my hobby and my work is audio and also vison. A system is just something to play music with, that is the essential part of it all.

Someday the B&W will officially join the ranks of Bose. Overpriced and hyped speakers that are easily bested by cheaper speakers by lesser known brands.
