I purchased a pair of 2405H that arrived in bad shape. So I sanded them down and repainted, now they look great!
Then I ordered and installed replacement diaphragms. Here comes the problem... the two tweets, both with new diaphragms do not sound the same.
I want to try to reseat/fuss with one of them but I don't know which one is off. Here are response curves of the two. I can't find response curves for this tweeter on the web so I don't know which one is closer to spec. Can anyone tell me which response appears to be more in line with what these tweeter should be?
Note: Measurement system not calibrated, and lots of noise in the room, but you get the idea.
