Believe you me. Start with a proper eval of your room by a specialist. Best 500 you will ever spend. ANYWAY you will need to do that if you want the smallest chance to integrate your subs.
1) Room measurements
2) Apply treatment
3) Add subs - yes, 2, not 1
I have Magicos. Subs are game changer. I learned that a while ago. I have two JL Audio S/510.
