There are those who say there are higher stands that work better, but I have found that these do improve the imaging of my 4313B's. It's the upward angle that does it. I found some minor discrepancies in the dimensions shown here vs. the actual stands I have, but pretty close. Also, the notch depth is missing from this illustration, the depth is 1" in all cases. Let me know if you have any questions. Good luck!

P.S. The thread shows the arms as being 2-1/16"wide. My stand's arms measure an even 2".
