I just bought two 12" drivers that weigh over 20 pounds and I am a little uneasy about the best method to mount them. I had planned to put them in the Parts Express trap cabinets but I am not sure there is enough meat there to hold them. I thought about putting a second baffle inside the original which is only 1/2" thick. I also thought about putting a block under the magnet but I am not sure how to get it right. I would appreciate any thoughts or suggestions you might share.
