Hi Bert,

I hope all is well with you.

I was interested to see that you are using a 4th order passive filter now. Having you experienced any problems with insertion losses with this? I ask because many people quote the use of PLLXO for higher orders as not practical so I never tried one.

I gave up with my third order one PLLXO (your original 150 filter), and now use a 4th order active device. But as I now have a good undertanding of which frequency cut-off to use for my set up, I'd like to go back to passive if possible.

Have you ever experimenting with a passive shelving filter to give a bit of bass to the lowest frequencies?

Kind regards,

Jonathan
