nautilus 801 bass accuracy


calling on 801 owners and anyone with many hours with 801's.... I'm trying to figure out if the lack of definition and boom on bass guitar on some recordings is inherent in the speakers or something I can correct. this quality or, lack of, is enough to want to stop listening. I could be exciting a room mode but at this point I'm not sure. Actually on some recordigs I can identify it as standing waves. other times it appears to be muffled bass from some recordings and it stands out because the rest of the sound is so great? I've noticed some owners on audioreview say if the source equipment is low standard you will get this? I'm running a AI mod 3 through 2 bryston 4bsst bi amped but my cd player is rega planet 2000 and turntable is an old planer 3 with clearaudio cartridge.
Your help is needed. Thank's

With a speaker the size of 801s, placement will be critical. Have you tried to measure the room w/test disc & spl meter? This would certainly be the best way to find out if the room & placement are the issue, or at least a big part of the issue....Cheers,

PS: lots of good info on rives.com on this topic
on some newer rock records the big fat bass sound is the way the recording is engineered. remember,most playback today is done in cars and on pc's.
How big is your room? Have you played around with set-up? Perhaps you have the speakers to close to the back wall? The sound you get from a speakers is always the reaction and relationship of the room with the speakers. If at all pull those mothers away from the back wall and make sure they are not too close to the sides either. Unfortunately, unless you have a large room ( bigger than 20 x 20 ) I do not see you fixing this situation especially if your set-up is not symmetrical.
What is really confusing is that you say there is a "lack of bloom and definition," and that is sounds like standing waves. Standing waves cause "bloom or boom", not the lack of it and most often is a coloration. Have you anyway to measure the speakers with something like a cheap RS SPL meter and something like Stereophile test CD?
If you have a small room or the inability to have a symmetrical layout with NOTHING in-between the speakers then I say sell the speakers and get something with less low bass extension but with an upper-bass tilt.
Also, make sure you speakers are wired in-phase.
