I setup my levels using 75dB limited bandwidth pink noise with my disc, then I went into REW and am checking levels using Pink PN from the CD player. I needed to raise my subs gain from -9 to -7, about where my other speakers are at. After my filters I raise the gain 1dB back to where it was relative to the level of my mains that the REW SPL meter is telling me. When I check in the RTA with Pink PN I burned using REW at -20dB FS I am looking for what I expected to be a flat looking line. I used my SPL Meter calc file. I'm supposed to use that right? Why does it look like I have a house curve when I calibrate the sub relative to the mains? I thought when looking at an RTA it is suppossed to be looking like a flat response in our graphs if we calibrate our subs flat, position our mains for a flat response. It would look like this if I were to measure a sweep also after setting levels. Please explain to someone that is new at this. :help:
