I'm not sure if the Rat Shack model is the same driver as the Fostex catalog unit, and a lot depends on vintage. I remember the Rat Shack FE103 was an acoustic suspension midbass back in 1968, and I don't think it's that one. Anyway, the current Fostex has an Fs of 80Hz and Qts of .35, so if yours are close to those specs they would work in my TLAH pretty flat down to 100 Hz. At the other end the off-axis starts getting hinky above 6kHz, the same as the drivers I used, so it's close enough there also.
