OK. I am not looking for tweaking opinions on my freq response, yet. That will be in another post soon - after some more testing/tweaking. Please excuse the non-standard graphs - for illustrative purposes only...
Anyway, I am am curious about way the VLF response (i.e. <10Hz). I have a RS meter and downloaded the date-corrected cal file (shown in the graph below). I have a BFD and have no plans of upgrading to something to allow a fuller range EQ (assuming they exist) anytime soon. My main curiosity is how much of this low output is real?
The cal goes to 7Hz and extrapolates to the low end from there. This is a 4x15" IB, so it can put it out down there - you can feel it, especially at higher SPL:
(yes, I wore hearing protection - I am not a loud volume guy anyway - my hearing is still pretty good)
If the RS meter tails off more than we think (or more than represented by the curve) at low HZ, won't this increase the measured SPL, because the correction values will be larger?
In other words, if you can measure it is probably there, but if you can't measure it, that doesn't mean it isn't there?
Is the meter so erratic that low so it is all garbage?
Thanks,
Pete
