Fragment wywiadu z Siegfried\'em Linkwitz\'em
"JD: Looking at your Orions, I can’t
but wonder whether that purposedesigned
analog crossover cannot be
replaced by a DSP unit?
SL: In principle, I am convinced that
it can be done. But it’s not trivial. You
need to measure and adjust the whole
chain, analog in to sound out. Now
someone may come up with an FIR filter
that makes everything linear phase,
but you get pre-ringing from the filter
and the sound may combine correctly
at one point in space but what about
off-axis?
You could use IIR filters to mimic the
analog filters, and that would probably
be my approach. Then I would first
make the amplitude response correct
and then you can do an overall phase
response correction of the complete
system. That’s how Bruno Putzeys
does it in his Grimm Audio two-way.
And I would not buy a standard DSP
box off the market. The devil is in the
details. But it’s hard, and it’s not on my
to-do list!"
