>>Randy : The second graph ... The 500 was centered right below the screen, below the VP150.
>>John : I suspect that if you stuck the EP500 in the middle of the wall rather than the left hand side that would take down the 38 Hz peak.
Hmm. Think I missed something. The second graph did have the EP500 in the middle of the back wall. I'm surprised that didn't have more effect on the 38Hz peak -- is there any chance the side wall to the right of the screen is very light construction compared to the rest of the walls ?
