I have M22's, STF-1, and NAD T742. right now I have the M22's set to small. the NAD manual doesn't seem to tell me exactly what the crossover point is. it just says set speakers to small if they are not capable of reproducing the deepest bass from 20-100hz. is it possible the crossover point is really as high as 100hz? the STF-1 crossover is 90hz and below, so if that's the case I am losing a 10hz band. should I being using the M22's set to large with the STF-1 crossover at 60hz or so?
