You would actually be getting the signal from your monitor mixing console or from front of house. This is sent to you just like an individual monitor mix. You can add whatever you like to your personal mix.
I have the Ultimate Ears quad drivers and they are great. A little on the expensive side but I've tried others and they just didn't reproduce my bass well.
Very nice Todd, I just checked them out. So are they custom molded? If so, how does that work when you purchase them?
He'll post pics when it arrives.
