Monacor WG-300 + Seas 27TBFC/G

Throat of wave guide is sanded until diameter is 40.5 mm. Pockets on the back side are roughened before epoxy casting. M4 x 30 screws with tee nuts are placed to the tweeter, screw heads 15 mm above the flange. Finally pockets are filled with epoxy (SP 106) and tweeter carefully dropped in place. Required volume of epoxy is about 1 dl per wave guide.
