RE: GPA Altec 414 alnico vs. MCM 55-1220 : WinISD

Those would seem to be my T/S measurements... I'm pretty sure when I originally posted them I explained why Fs and Qts usually test high for me (drivers not broken in and sitting face up on the dining room table). Originally, and here again, take them as a single data point.

In any case, GPA publishes the T/S for those drivers. Again, use those and not mine.

I have mine in 4.5cu ft, tuned to around 28hz. I like them an awful lot. Keep in mind my amplifiers have 2-3ohm output impedence.
