LIMP Data Dump

JasonP

Well while I still need to design and print the adapters for THD testing, I decided to do a sanity check and run most of the drivers I have sitting around here to make sure they work. I figured I might as well also post up the graphs as a bit of a teaser for the upcoming hard data dump. Here are the drivers I tested of the ones I have lying around (no tweeters yet):

• Tymphany TC6FC02-04, a quad. 2" full-range https://www.tymphany.com/transducers/tc6fc02-04/
  
• Tymphany GBS-85N25PR03-04, a quad, 3" dome woofer  https://www.tymphany.com/transducers/gbs-85n25pr03-04/

Oh, and of all the drivers above, only one of them was properly broken in. Bonus points if you can tell which one.

Looking closer at the graphs, I can see why you'd think that. But actually it is one of the 4 TC6FC02-04 that I actually ran test sweeps on a couple years ago. One of the four is far different, and that is the one that was run.

I was guessing based on the age of the drivers
