Well one of them at least, i messed up the holes last week for the other. I put this on left channel with the Pioneer 737 for power. Against my KRK Rokit 8 active monitors. PWNED !! Wow what a difference even with my jury rigged X-over, This isnt a "OMG this thing i built kicks butt" comment. I had friends sit in the middle as well. We got it as close as possible to similar SPL and then played one song. Completely dwarfed the KRK which are built for NF but none the less. Man i cant wait to get the other one fixed and see what this baby can do without the subs.
