my problem is my speakers CAN play down to 60hz, as they were playing that low prior to installing the ms-8
and i know it was not something wrong with the crossover on the amp because i had run test tones, so it was a legitimate 60hz
the specs say 55hz
my 4" logic 7s were ok down to 90-100 (not sure as its not labeled on the amp)

i think its also a function of how much power you are giving your speakers
if you are hooking them up to 100watts rms or more, i doubt my speakers could handle 60hz, but i'm only giving them 50watts.

Remember that the sub level control also boosts the midbass ABOVE the xover point.
is it a problem if i have the subsonic at 20hz at 6db, then run that signal to my amp and use my amp crossover?
my concern is i know some orders of crossovers inverse the phase
so i don't want to get into that
because it would be 6db from the MS-8 and 12db from my amp. (so 18db total)

why would the sub level affect the midbass above the crossover point?
i'm just playing with the gain on the sub channel
