If you can't get "loud" with two 15" Mag's you have serious issues to address. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Loyd is doing serious numbers with his two 12's, Scott Stoner did 150 with a single gen 2 Mag in a wall with 1200 watts, Hoss was pissed when he would do a 150 because his normal was a 153 with four claw Mag 12's, Chad with his new Mag 12's, Sean B. with his two new Mag's, etc, all did/do extremely well. In the right alignment our Mag's can get nasty loud, and conversely they can do double duty for a more "SQL" approach if you want it to. My 'teggy is doing mid 140s with two Mag 12's in 1 cube each sealed. Two Mag 15's in the right enclosure can do serious harm to an SPL meter AND sound good for daily driving.
