the audiobahn might get louder. But I had a pair of AW1005X's that never even got into the ballpark of one Ed12o.44, I had two audiobahn 'natural sounding' 15's before and both of those never even came close to one 12O again. Keep in mind the 15's were rated each at 500 rms like the O, and the tens I had were 1000 watts rms each. Just my personal experience take it as u like it.
ALSO you're working with a sealed enclosure. Quite obviously the O will perform better in the sealed application than the audiobahn will. I took those aw1005x's out of a ported box and put them in a sealed and, while the bass cleared up a LOT, I lost half my output. $0.02 there you go.
