Ok, I got the single RF-3II. I took the drivers out fairly easily. Problem is, I CANT FOR THE LIFE OF ME pound the motor board off. It seems like if I try to the liquid nails would rip some mdf from the cabinet, which would probably cause a problem with air leaks. Perhaps if I put a wood pole through the port in the back and pound that with a mallet it will come off. Or are there any other methods that would work to get the motor board off? Also, how would I make...the rabbited edge to be inserted into the box...the rounded square shape of the woofer outer edge...and the slightly rounded edges of the sqaure at the outside of the tweeter. Just use the old board as a template? And tell me exactly how much liquid nails to use when putting on the new board. THANKS!
