I reviewed my "e" mail from last November and here is what Brian at firstname.lastname@example.org said "This tweeter is still being built, but with a round flange as the TW025A0. You can buy the TWO25AO and put your old rectangular face plate on the new tweeter. The screw holes line up".
I didn't get them and try it because mine still work but I thought due to age that I might want to replace them.
Hope this helps you out.
P.S. If you ever need to have the woofers redone I had my rebuildt by Millersound located in Landsdale, PA. The phone number is: (215) 412-7700.
