So does anyone know anything about how you are supposed to mount the 11inch spider adapter on the tooled frames. The thread is m4×.70 bit the hole on the spider ring is almost a 1/4 wide. I'm assuming they need to be flush mount or recessed. Only problem with recessed is unless it's just pressure fit, the hole is one diameter all the way thru. And this is where you will be gluing the spider now. I am currently turning xv315 into 18 and don't have a complete sub to look at. Thanks in advance
