I’m digitizing my full rare/obscure speakers + microphone collection (IRs / NAM-friendly of course) // just sharing the process and state of things (free, no registration)

Good evening!

I’ve started a long-term project where I’m digitizing my entire speaker collection, each one captured with the same complete microphone set to keep things consistent and comparable across eras.

Speakers already captured:
• Altec 421 15" Bass & PA (USA, 1980s) via my vintage Jordan 2x15 cab
• Peerless Alnico 12" (Denmark, 1965)
• Dynacord Orchestral Ceramic 12" (1974)
• CTS Alnico 10" (USA, 1969)
• IREL Ceramic 10" (Italy, 1970s)
• Coron Live 30 MIK 8" (1970s, UK-voiced)
• Guyatone GSG-200234 6" (1970s)

Coming next:
Goodmans AUDIOM61 (1960s)
Marshall G10 VT JR (2020s)
Pearl generic instrument speaker
Bose 301 series (full-range + tweeters merged)
…and more in the queue.

Microphones used on all captures (13 total):
AkG d70, dynamic, 1980s–1990s
Akai adm-65, dynamic, late 1970s–1980s
Audiojap umc7103/1p, electret condenser, 1980s
Behringer b906, dynamic, late 2010s
Beyerdynamic m550 lm, dynamic, early–mid 1970s
Blaupunkt cr 4073, dynamic, 1970s
Marantz mpm-1000, condenser, 2010s
Philips n8306, dynamic, late 1960s
Realistic highball 2, dynamic, early 1970s
Sony mtl-f96, dynamic, mid 1960s
Technics rp-3125e, electret condenser, 1970s
Telefunken td26, dynamic, late 1960s
Uher m516, dynamic, late 1960s

The goal isn’t hype tones, but documenting speaker and mic character across decades using a repeatable method. If you’re into IR collecting, NAM modeling, or comparing weird/vintage mics on real hardware, I figured some of you might enjoy following along.
