In the past, I noticed that I prefer a well implemented passive crossover to the DEQX ( mid to tweeter ).
Never gave any thought as to why, just accepted that in an apples to apples comparison, the passive sounded better.
Had an interesting discovery this evening.
In general, the DEQX will correct the mic’ed FR within predefined limits that are system and user adjustable. While the system will adjust the lower limit depending on various variables, it doesn’t adjust the upper limit, which is set at 20K from the factory.
I was playing with the upper end limits on the DEQX this evening and for grins, set it not to correct the FR above 3K, and guess what, it sounded better uncorrected.
In wondering why, given that many FR variations above 3K are baffle related and change as one moves off axes, correcting them as the DEQX does on one measurement axes, would likely cause issues elsewhere. Given that most passive tweeter crossovers do not EQ much if anything above the crossover region, I wonder if this is the key to the passive sounding better?
Will have to break out the speakers that sounded better on passives and retest.
