In a 5.1 setup, what is the difference between setting F, L and C to LARGE with the crossover at 90 and the SUB to SWFR, what's the difference between that and seting F, L and C to SMALL and the crossover to 90 with the SUB to SWFR. The rear surrounds are set to small in both senarios. Even though they are set to LARGE all frequencies under 90 are being set to the SUBWOOFER. Is this an incorrect assumption?
Any response will be helpfull.
