I was wondering if anyone actually tried to calibrate their sub using he waterfall decay instead of FR graph? What I meant was that looking at the waterfall, there are usually certain freq where the decay is much longer then the rest. And subjectively these decay seems to hang on in your room. So what can be done is find out the exact freq of the long decay and do a EQ setting to reduce it and remeasure till the decay at the level is close to the rest of your freq. |
Ideally you should use both. Generally the peaks in the FR curve will have correspondingly long decay times in the waterfall, so fixing one fixes the other. However, the waterfall (or the spectral decay) curve can be better for identifying cases where what looks like one peak in the FR curve is actually due to two closely spaced modes, which become visible as separate peaks in the later slices of the waterfall or spectral decay.
