TOPIC:

If the crossover's LPF and HPF filter can both work within about 300 taps, then it doesn't matter which channel is used for high or low. However if any EQ is needed lower in frequency than the crossover, then it's highly likely that this EQ will need more than 300 taps, and therefore the LPF and low EQ needs to use the 2300 tap channel.

Kind regards,
Michael

How long are 100hz and how long are 300taps?
it is to short...

if you use FIR filter right you will resive a much more clean sound
your hearing is very sensitive in your crossover sektion so it is recommended to do it perfect as possible this is only doable with FIR...my point of view...
please correct me if i m wrong but i think an ESL has an phase shift do the nature of an transformer this is almost impossible to fix with IIR filter

the calculiton is only to find roughly an alignment
it is absulutly necessary to check the phase response of both speaker and anlign it manualy
speaker are never perfect the calculation cant be the final answer

if you like to get advanced help we need measurments
all other are guess and thoughts


best regards
