Question: I need to modify an active stereo crossover that has the filters on some plug in cards.
The low pass filter is configured to 100 Hz and I need to bring it up to 400 Hz to match the speaker characteristics.
I am wondering which device to use for this measurement. I can certainly generate noise with my function generator and feed it into the input of the crossover, however I would want to check the output for the optimal filter characteristics (dunno if I am expressing this correctly in English, sorry, me bad ...)
Most spectrum analyzers start at 9kHz, which does not give me any results for a low pass.
Which analyzer would you recommend ? It should be in the somewhat affordable price range.
Thanks
