I finally had the time to measure the (2) E-140's that came with a pair of Cabaret 4691B's. I hooked up the WT2 and here is what I came up with. Both were measured in the same environment:
Revc 4.9 ohms 5.2 ohms
fs 31.5hz 29.0hz
Qes .21 .15
Qms 2.3 4.4
Qts .19 .14
Zmax 58 ohms 156 ohms
Le .92mh 1.26mh
It seems that the left column driver is pretty close to original spec while the right column seems to be pretty far off to me.
I thought I would use these for a project, but it seems to me with only one measuring worth a sh*t that they might be better used as cores for 2235 hybrids.
If I had to guess, one of them was reconed and the other one much older(and maybe had too much beer poured on it. It even sounded different when the cone was tapped with my fingers prior to measuring them( I do that sometimes to give me a quick evaluation of a drivers condition).
I did not have a cabinet handy for measuring Vas and Eff, so I'm sure they would be off also.
Bummer!!!!!!!!!!!!!!!!
What do you guys think I should do here??? Are these too far off from each other to be capable of putting out a matched sound??????
I would not have bothered with these had I known in the first place the condition of these drivers.
I wanted to use these for my Edgar midbass horns when Bruce gets them built and delivered to me in the near future. This kind of makes the E-130 framed 2225 recones a candidate for the Edgarhorns.
All comments welcome, I'm bummed.
