I finally bought a SB External USB soundcard for my laptop. I think that fixed the strange graphs I was getting before. This is my first real attempt at REW. Any tips/suggestions are appreciated. This is after EQing with an Ultracurve Pro. Also, how do I narrow the frequency shown on the graph like most do? The graph is from my dual VTF3 MK3 with turbos. I calibrate the mains to 85db and the subs are 3db hot. Graph is subs only, btw.
