SA-12 D2 T/S Specs

[sundownz 197]

Minimal break-in time... just a few minutes on the bench:

RE (Series): 4.33 ohms

Fs: 30.3 Hz

Qes: 0.519

Qms: 7.250

Qts: 0.484

Le: 4.743 mH

Vas: 29.077 L

BL: 22.168 NA

Cms: 89.22 uM/N

Mms: 308 g

Took a few minute break from shipping 4500s and measured these bad boys... I expect Fs to drop to 25 Hz or so with full break-in... which will take probably a week or so of play on these.
