Hi all, First off, this is not meant to be the typical crossover setting type question. Take a look at this article. On the lower left corner of first graph are freq response curves for a subwoofer, measured at different sub-level crossovers. As the crossover is turned down, the freq response flattens. My question is, has anyone deliberately turned down their sub crossovers to flatten sub frequency response? Any insight/tips/tricks on doing this? FWIW I'm running an HK 320, PSB Alpha Bs (good down to about 55-60 hz) and a Paradigm Pw-2200.
