In Reply to: Why the "A" response scale? posted by bstan on January 6, 2002 at 10:00:08:
at the same time, since the pink noise is pretty much random. So for sub adjustment, you would never know the real SPL of the system. Unless you figure out the bandwidth and distribution of the pink noise, do a weighted response drop of the meter for that freq range, and compensate for that. Plus one might have to compensate for the premature rolloff of the sub, since if the sub is not producing any sound below 30hz, the level will be boosted by the person to bring the whole level up to 75dB.
That is why I recommend doing the level matching @ crossover freq, plus plot the whole sub range and maybe mains to 200hz see the integration.
