my thoughts

Hey Spanky!
Tom Here! (your friendly drummer from Mansfield)

I was hoping someone else would answer to get more ideas but I had 2 ideas.

The first thought was the same as the previous post.
If your speakers are now located close to half the way between the ceiling and floor, or if your listening position is now half way from one boundary to another, and there is not adequate bass absorbtion, then you are probably getting some cancellation because you are now in a null.

My other thoughts, are when spaeakers are close to a wall you get a bass boost that you may have gotten used to, but now listening with them further away from the wall you are getting a more realistic picture of what you actually recorded.

Hey Tom, good to hear from you - thanks for the reply - which speaker ( woffer, tweeter for two way or, in my case three way ), are you talking about? - also, you are probably right about the null in the listening position - I'm sitting almost exactly in the midle of the room - I have all of the dimentions of the room, I just need to post it - I suppose it would be easier for some one to help. I will try to post drawings in the next few days. Thanks for the help!

Placing the speaker near a node (null) can actually help the room response. A speaker drives acoustic power into the room. It is naturally an anti-node. Placing an anti-node at a nodal position will help break up the room modes, making them more complex and diffuse.

Yup. Just 'cause you're used to it, don't make it right.
