Please help me tame the bass beast

I own the Joseph Audio RM50si's which go all the way down to 20Hz. My preamp is the Classe SSP-75 and the amp is the Classe CAV-150. CD is Sony SCD 777. The 75 does not have controls to turn down the bass level. What can I do accoustically to eliminate such an annoying rumble in the mid bass. I moved them around the room but nothing seemed to really make a difference. Is the problem the amp or the speakers or the room. I have read reviews on this site and people seem to think Classe amps deliver a lot of muddy bass. The low bass frequencies seem to be okay, it is really the mid bass that is the problem. If I sit really close it is better but not great. What can I do?? My room is rectangular 18x12. Please offer me some suggestions. They are great speakers except for this problem.

subwoofers. they will work well, even w/full-range speakers. they will allow you to place your main speakers optimally for image & soundstage w/o regard to bass response - use the sub(s) for that. my subs were effective even w/my old thiel 3.5's, which were rated -2db @ 20hz. passive subs (i like vmps) an active x-over like a marchand xm-9, will allow for a seamless blend w/most any monitor, full-range or otherwise...

one caveat - your room may perhaps be a bit small for a truly full-range speaker, & even optimally locating a sub may not help. i also suggest you look into some sound-treatment, like tube-traps, etc...

I don't know what you could do acoustically that wouldn't take a lot of trial and error on your part. But you could probably fix the problem easily via a digital processor like the low-cost Behringer 8024, or a more expensive TacT product like the RCS 2.0. If I were in your shoes, those are the options that I'd be considering. Good luck!

I wonder what stands do you use if any. I have Totem Forest speakers that are standing on the 3/4"MDF platform with their original ball-feet and the platform is placed on the vibrapods. That setup brings more natural bass and eliminates floor resonance.

The floor resonance might be your problem.
