I replaced a horn diaphragm in a 846B for a friend. Although I never would have considered using an aftermarket part, he ordered one to save a few bucks.

For the most part it looked the same and they claim everything is the same as the original, but the connection terminals were different. That issue was easy to get around.

We installed it and gave it a shot.....

NASTY!

The repaired (if you can call it that) speaker is significantly brighter sounding. I say brighter but I would call it annoyingly harsh. There is a noticeable difference between the two speakers now. At first I thought maybe the old original might just be out of spec and we should have replaced both at once, but thats not the case.

That aftermarket diaphragm sounds like hell.

This was my first (and last) experience with an aftermarket Altec part. There may be better aftermarket parts for them out there and you guys with more experience may know of some but I would never chance it with mine after hearing this.

Fair warning to those of you considering any aftermarket replacement parts. That one is getting replaced so trying to save some money wound up costing almost twice as much.
