Re: What Will Sound Better 4 12" kicker comps or 2 15"...
"One drawback to the 15"'s is that you will need reasonably good and loud midbass since they should be crossed over lower than the 12"'s would need to be."
I don't think this is an issue. A good 15 will go to 800Hz and a good 12 will go to 1100Hz. Not so good versions should probably be crossed an octave below these frequencies. 400Hz should not be a problem for any half decent mid range driver. Most mid rangers will go below 200Hz.
