Good question bestbang4thebuck. I am thinking of using 3 subwoofers, one each associated with the FL, FC & FR to give me full frequency response from 20Hz to 20KHz on these channels. If I set my 3 front speakers to large and do not use a sub on the .1 channel will I be missing anything? I wish that the Outlaw manual would cover all of these situations or is there some other generic document that covers this stuff? Thank you ---- Thank you very much. Reed
