The mounting plate has curves for two speakers (not sure which) but didn't match mine. Every time I tried to tighten the clamp the block would move down the front (also partly because the clamp pins were set wider than my speaker. Put it back in the box to go back (but I really didn't want to ) and then I figured if I was going to install a curved stabilizer bar for my column and between the pins. So I cut out a piece of 1/2" ply to fit my curve and slid a bit between the column and the clamp pins. Sanded it down a bit after testing, I adjusted it to just cover the original clamp plate design for my template to use, secured it around the back of my template, around the pins and around the pillar - and it is now aligned ps make sure your stabilizer is cut off the outer template so it doesn't get in the way outside of the pin also tilt the corners of your template and round Pull them off slightly as the clip will also bypass them.
