The equipment in question--SVS 25-31 PC+, Sony DA4ES. When I calibrate the sub volume using VE and RatShack SPL with receiver volume set at -20.0 dB (max 0 dB) and sub located approx. 6 ft from the listening position (6 ft value also inputted into receiver), I find that I have to set the receiver's LFE output level at -15.0 dB (-20 to +10 range) and the SVS volume knob at 2 clicks (out of 8) past minimum in order to hit the VE 75 dB reference level on the SPL. So...even though I can set sub reference at 75 dB and granted that the sub is fairly close to the listener as it is, why do I get the feeling that the LFE output is gonna be pretty low (volume-wise) when I listen at "normal" levels, e.g. receiver volume set between -50 dB and -30 dB? I mean, the SVS' volume knob is only 1/4 (meaning I could crank the knob quite a ways if I wanted lots of LFE output) and the LFE output level on my receiver is set at only -15 dB; not only that, the LFE trim on the Sony is set to -5 dB (-20 to 0 range, IIRC). I can only imagine how much more bass, albeit distorted, I could get if I cranked the LFE level on both the receiver and the SVS to just only the midpoint on the adjustment scale. So I guess what I'm trying to get at is this: Which is more preferable--lower receiver reference volume with higher speaker level adjustments, or higher receiver reference volume with lower speaker level adjustments, when calibrating, and why?
