I have been using a E120 ceramic original cone for a year now and just love it. Based on that info I just purchased a used D120F Alnico apparently with a poor recone kit from the 80's (Waldom I believe) So here are my choices for recone A) Factory original E120 kit with cloth surround B) A after market D120F kit with paper surround from orange county who has them made just for them, and is suppose to be a perfect copy of the original C) There is a guy in Nashville area who is very famous for JBL recones. He offers 2 recones / a factory JBL E kit or a aftermarket E kit. The aftermarket does not attach the 4" aluminum Dome to the voice coil like the factory kit. The Nashville dude say people who have heard both kits prefer the aftermarket one. We are talking about some heavy hitting guitar players. Help any info would help in my decision!!!!!
