Ran across your system this morning and noticed the VR4jrs which is the same speaker I am using along with some timbernation platforms. I saw on your thread that you were using the spikes but I didn't see whether the speakers were loaded with lead shot. I originally had 25 lbs. of shot in each speaker but I just added 25 more and put them on the platforms. This really tightened the bass in my setup but I can only pull the speakers about 18" from the back wall. Fortunately I have no side wall issues.
Nice system!
