You're the same person that said in your original post about your B&W 801 series 2 that the electrolytic capacitors that were in parallel and not in the signal path would not degrade the sound. Little did you know your old capacitors would lose capacitance therefore reduce in value by up to 20% changing your crossover frequency. You were asking elementary questions about a passive crossover three months ago and now your designing active filters. I was born at night but not last night. Nice Try
If you can design an active filter, you can answer your own questions when it comes to a passive crossover.
Your bass alignment filter has a high commercial value, But the more valuable factory B&W sell on eBay sell for less than $200 and whoever built them for you used a Cheap Chinese case bought of eBay so do the Chinses cases also have a high commercial value?
And the factory B&W have the power supply separate from the actual filter to stop any stray electromagnetic fields from the transformer from creating unwanted noise in the filter. Did you forget about that in your design I mean the guy that built them for you forgot to separate the power supply from the active circuit. Or was that you that forgot?
So, what's the filters alignment is it a Bessel alignment? or a Butterworth? what frequencies are you I mean the guy that built it filtering.
Surly you the designer knows the answer to this very simple question. Or do I have to wait until you talk to the builder tomorrow to get an answer?
