grill magnet sizes different?

[tomzarbo]

Has anyone used the neo magnets used for holding grills and found them to have different diameters?

I'm finishing up my entry for this year's dayton speaker meet and just noticed that half of my magnets (8) are ever so slightly smaller than my other 8. I ordered these a few years ago and am just getting around to manufacturing grills for these speakers. Glaciers move faster, I know. Half fit real snug in the hole, the rest are a bit loose. No biggie, I'll make do, just wondering if others remember a similar issue?

These magnets from PE used to be 3/8" in diameter, which meant they were 0.020" smaller than what is currently sold. I remember there was a time they were still listed at 3/8" diameter but actually were 0.395". I suspect you've got some of both diameters ordered at different times.

In fact those magnets are and have been for quite a while 10mm.

True, but there was a time after that changeover when they were incorrectly described as having a 3/8" diameter in the listing title, but were correctly described as having a 0.395" diameter in the detailed description. I bought quite a few of the 3/8" diameter, and when they changed to 0.395" I stopped. I now buy from a magnet source neo magnets with a 5/16" diameter and 1/4" length.

Well thanks, at least I know I am not going nuts. That must have been what happened. Also, onensize is more shiny than the other. I guess I'll just use what I have. I will also use a few of HFT's neo magnets as well. They are cheap!
