Does someone have the T/S specs for the 127H-1.
I can find them nowhere.
Here's what I have Guido:
Fs = 31 Hz
Z max @ Fs = 138 ohms
R1 = 29 ohms
F1 = 23.5 Hz
F2 = 42 Hz
Qts = .357
Qms = 8.077
Qes = .3735
Fsb = 75.4 Hz
Z max @ Fsb = 120 ohms
R1b = 27 ohms
F1b = 66 Hz
F2b = 85
Vb = .8 cu ft
No = .87%
SPL = 91.58 dB
Cms = 6.8E-4 M/N
Mms = 38g
Bl = 11.07
Le = .76 mH
Re = 6.1 ohms
Vas = 4.0 cu ft
Greg ran these numbers back in early 1986.
Aren't these the same as the 125A's?
No. The 127H-1 was used in the 4410.
I know they are different woofers used in different speakers, but just want to make sure these are the right specs. I was given these exact specs for my 125A's.
Then they must be right ;)Quote:

Therefore I recently refoamed two 127H-1 and found while adjudsting the signal generator for break in that the Fs should be around 35 Hz.
Will measure mine after breaking in.
With the original data I'll be able to compare my work to the true specs.
