Re: Virtual SMAART training: Tell the crossover frequency and type
I think I may be totally in the SWAG guessing game, but I am not really sure if the logic is reversible:
i.e. if A (an electronic crossover) creates B (an acoustic crossover), then by looking at B (an acoustic crossover) you should be able to determine A (an electronic crossover)
however:
1. either 90 degrees or 270 degrees of phase shift make me think odd order. I think I am more comfortable with 3rd order (18 db per octave) than 1st order.
2. The roughly-3 to -5 dip at the crossover in frequency makes me think gentle shoulders, i.e. Bessel filter
So my SWAG is 3rd order Bessel at 2000hz.
edit- and for the record, I don't think I have ever designed a crossover totally on my own, although I have tweaked factory recommendations.
