Do the sub crawl, find the best spots to place the subs. If necessary, place both subs in the best location. I would go for the position that gives the highest output especially in the low bass. Then use a equalizer to flatten the bass. That way, you have the lowest distortion and highest headroom.
Like anything else in this hobby, its critical to me, and not so much to everyone else, but I'm seriously considering a second..... or perhaps a VTF15.
