Before moving last month, my maggies were set up in the family room that was open to the kitchen. I would sit about 13 feet away. When no one else is home I would turn it up as loud as I can stand and the maggies performed flawlessly for me. The loud volume did not sacrifice any clarity or shrank the soundstage. The weak link on the system is my 15 year old sub that would rattle at the large explosions. I do not have any spl measurements but the sound level is as close to being in the theater as I can get it. I now have my HT set up in a separate but smaller room and I do not have to turn it up as loud to get to these levels. I am using a 7 channel outlaw amp (the 7075) rated at 75wpc and I think it gives adequate power.
