Hey Everyone, I have medium-grade woodworking experience. Recessing round drivers into a front baffle is relatively easy, and I've even made a plunge router jig to do so. Can someone point me to a "How To" where I can learn how to make odd-shaped driver recesses for flush mounting? (eg. DW-654S, Eminence Delta Pro-8B, B&C 8PS21, etc.). Thanx.
