Some questions about crossovers:
1) There are several excellent crossovers offered for Cornscala type speakers,
but much flexibility on the drivers- Seleium, BMS, etc. Don’t the crossovers have to match the complex
impedance characteristics of the specific driver? I assumed that at this level of performance the two need to be carefully matched.
2) I see references to changing taps on the autotransformer
to match levels. Doesn’t this change the impedance as seen by the crossover,
and therefore the corner frequency
3) While we’re at it, why autotransformers and not resistive
Thanks for any insights.
