The coil was not centered on the board and would not fit properly, about 3-4mm off. I had to dremel the board to get it to fit.Sounds very poor too.

I used them to repair tweeters in my pictured over twenty year old Cerwin Vegas V35 speakers because I was going to sell them. Now I am having second thoughts. The sound brightness that diaphragm tweeter repair gave those speakers is like night and day.Would Buy AgainD.J. Doc Lane

Do not waste your money on this product. I bought this to repair a dead tweeter in one of two PA speakers. The other speaker was fine, so I could compare the repaired unit to the original. Although this item was supposed to be a direct replacement for the original, it had only approximately half the volume and no where near the sound quality. I threw it in the trash and will have to find a different replacement.

Not exactly a perfect/OEM fit for my Goliath III JR, had to be forced in a bit....bending one of the edges. But, it works - sounds like it should.Also - shipped via ground even when advertised as Prime.An inexpensive fix for my Goliath III JR after somebody plugged a 1000W SVT head into it, cooking all the drivers.
