Excerpt: I am using it to replace some older JBL's MP225's that I had rewired to bi-amp. I was looking for something lighter and powered. I set them up in my garage to do a small test. I just set them right on top of my sub's two double 18's Peavey QW's with 8ooo watt's pushin em switched them to ext. sub and they kept up with no problen! I carry a DB meter to set levels when we are in a small room drove them to 124 DB and they didn't even clip.
