I've got spc4's and a short t bar. Most configs are fine, but to get x/y I have to run one mic on each side of the t-bar. This creates roughly 8-9 inches of vertical spacing between the caps. Is this too much for x/y? I guess what I'm asking is, will this be a noticeable difference from running x/y with the caps more closely spaced on the same side of the bar, via some sort of riser.
