HPF/LPF list- which do you use or know about?

And... this is serious stuff:

"...which offers 2 specific and separate filter networks, HPF and LPF filters with on/off switching..."

• HPF: 30Hz – 200hz
• LPF: 1kHz – 14kHz
  
  
  
  
  
  I can't find the info about the attenuation slopes, but knowing what previously designed @agedhorse , the low cut could be a 4th order filter with a fixed and a variable freq. points.

Thanks to @ardgedee for sharing this in the If HPF’s are such a trendy thing now...:

I use one of these. Hand built in the UK to what looks like an Fdeck design(?).
