This idea of the house curve for equalizing the 20-80hz range brings up a few questions for me. First off, +6-8db at 20-32hz is quite aggressive. I tried it today using my ART351 EQ by adding 20hz +6db 25hz +6db 31.5hz +6db 40hz +4.5db 50hz +3db 63hz ++2db 80hz +1db The THX Phantom Menace trailer was hitting peaks of 110db and the red clip light was flickering (first time I've seen it flash). Now, using this "house curve", do we want to be calibrating without the extra "hot" amount (2-5db on LFE)that we typically add? Perhaps even a bit under considering that the rat shack meter readings are incorrect in the lowest few octaves? What about listening levels? If we always listen at 10db below reference, what sort of setup do we want? What about if we listen at full reference? I'd like to add that the SVS ISD upgrade has really pushed my 20-39CS to a much higher level of performance. With the old driver this intro was just a bunch of clacking or else it wasn't loud enough to get any impact. Now it incites giddy/demonic laughter when the LFE hits.
