PROAC D48R Bass Booming

Dear all,  I have just bought a pair of preowned Proac D48R speakers.  I really love these speakers very much.  But the only problem is Bass-boom and because of that, some tracks are unlistenable.  My room is 17 L, 11 W and 10 W.  My source is Ayre CX7EMP and I'm having a Balanced Audio Technology VK3000 SE HYBRID INTEGRATED Amplifier.  Please let me know whether I can solve this problem.  I there any benefit,  if I change my amp and replace it with a Cary Audio SLI100 Tube Integrated amplifier.    Thanks in advance.

To to a local @home, Hobby Lobby or other store that sells artificial plants.  Buy four of five large, leafy artificial plants and position them along the back wall, and between and behind the speakers.  Don't be afraid to use 6-foot or taller plants.  These will act as diffusers and help to reduce the boominess.  Add or remove the plants until you get the correct balance.

Another possible suggestion is to place the speakers asymmetrically in the room. Have one speaker places closer to the side wall than the other. One speaker closer to the back wall than the other. Move the listening position so that the speakers are equal distance from the listener and the listener is facing between the speakers.

The logic behind this is to not place the speakers in a position to reinforce the bass by interacting with each other.

I personally use a set up similar to what I have described including the use of five large leafy artificial plants behind the speakers. It took the bloom / boom right out of the room. Tone balance, timing, dynamics, imaging and detail is now superb.
