Cambridge Audio SX-50 crossover freq and filters

[Darek K]

In his video

OCA says I need to enter the crossover frequency and filter type. I don't know where I can find the crossover data for the CA SX-50. Only chatgpt says the crossover frequency is probably 3200 Hz.
What if I can't find the crossover frequency and parameters?

What are you trying to do here?

1. You should know my english language skills are very simply. Just think about me like this "he is disabled human"
2. Because of this when OCA says something I try to reproduce this step into my step. When he is talking about physical crossover I search information about my crossover.
3. I have minidsp 2x4HD, hi is speaking about minidsp
4. As I assume general idea of this video is to produce FIR filers and put this in minidsp console.
In his videos I can know "what to do" (because it is visible on the screen) but not "why to do".

Maybe some advice from which minute "what to do" begins.

Thanks.
Darek

If you’re trying to make the speaker active, you really need to make measurements of the individual speaker units first, then determine the crossover point based on frequency response, off-axis response, distortion measurements, to determine the best compromise between directivity and general performance. Only then the actual integration starts, and here the crossover frequency is only part of the whole set of things to consider.
