[QUOTE="atbear, post: 8558938, member: 646132"] Building on my original post, is my thought process right on these two scenarios related to a perceived boost due to overlapping frequencies between the mids and subs? I read where about -30dB is where a boost becomes imperceptible. Is that right? If so, PerceivedBoost below is showing how much above -30dB these overlap induced boosts are...
