This is my system with new stand
I didn't make any adjustments to the stand and just ordered as listed. Got a bit lucky as everything fitted, although the end spaces aren't wide enough to take full size equipment. As you can see I have two big spaces going spare.
My thoughts are to replace my sub that's n far left of photo with 2 x BK XLS200. They'd fit in the gaps n the stand and make everything neater.
PI know its not really done thing, but with sufficient isolation is it really such a bad idea.
