The obvious benefits of an HPF have interested me for awhile.

 

A few years ago I borrowed a Thumpinator and used it with an Aguilar TH500 through 2 Berg AE112's. I noticed very little difference with and without. I didn't see any change in the movement of the cones.

 

At the moment I'm running a Berg Forte HP through a Super Compact and sometimes with a Super Midget as well, and I still don't hear the HPF making much of a difference. The point where I can hear the HPF working it's changing the tone in a very unpleasant way, making it thin and nasty.

 

Is the HPF doing its job when I can't hear it? How do I know if it's doing anything useful not?

I measured last year some stuff of my chain. My Aguilar Tone Hammer 350 (the preamp is the same of the 500) has an HPF fixed at 20Hz, -3dB, slope is something between -6dB and -12dB/octave (if my vision is correct here). ARTA software graphic pic attached.

We maybe aren't hearing if the HPF is doing something because it's working below our hearing capabilities.

Shame on you, FB.
