I guess I don't need to set the mains to small and apply a crossover after all... I think? If I want to add a subwoofer for my 2 channel music that needs a little extra bass, I guess I can just change the sub from LFE to "main +LFE"
will this option send the bass from the mains to the sub kind of like having the mains set to small with a crossover?
If this is the case, I wonder what frequency the cutoff point is for what stays with the mains and what goes to the sub?
I think I am a little confused on the difference between setting the mains to small with a crossover, or leaving them at large with the sub set to "LFE + main"
