Inside various electret microphones

Hi,
I've been looking into linkwitz modding some electret microphones (curiosity) and ended up taking apart 25-30 various modern capsules (available from Mouser and Digikey). Some of them seem to be easily modifiable.


The list so far is:

  • AOM-4546LR
  • AOM-5024L-HD-R
  • CMC-2242PBL-A
  • CMC-2742PBJ-A
  • CMC-2742WBL-25L
  • CMC-5042PF-AC
  • CMC-5044PF-A
  • CMC-6027-32T
  • CMC-9745-37L100
  • CMEJ-0413-42-SMT-TR
  • CMEJ-0415-42-P
  • CMEJ-0627-42-P
  • CMEJ-0627-42-SP
  • DOM-3027L-HD-R
  • EM-6022P
  • ICS-40720 (only macro photos, without teardown)
  • ICS-40730 (only macro photos, without teardown)
  • ICS-40740 (only macro photos, without teardown)
  • MO063602-1
  • MO064001-1
  • MO064002-3
  • MO064402-7
  • MO064404-1
  • POM-2244L-C33-R
  • POM-2730L-HD-R
  • POM-3535L-3-R
  • POM-3535P-3-R
  • POM-5038P-C3310-R
  • POW-1644P-B-R
  • PUM-3046L-R
  • PUM-3546L-R
  • TOM-1545P-R

I've uploaded them to my imgur: Imgur: The magic of the Internet
I might upload them here, if there is some interest.
 
Hey there.

I assume that if you were looking at linkwitz modding these you were looking at recording or measurement application.

Did you measure frequency response and do you have any recommendations on better options for measurement mics?
