Well I picked up 10' of 6" pvc and waiting on argent to get a quote for the flares but if I cannot get a quote by next week, I'll just buy them somewhere else. I may not have two 18s to play with now because after reconing both the 18s, the ixl still had slight rubbing or some type of noise when I pushed down on the cone. I really don't know why. I checked gap and spacing and there was no motor damage so i cannot figure it out. However, I can always do a 12" build for music if I need more up top from the avalanche.
