Is this what you have?

I have a tri-amped TL system, using 4th order XO filters...

It's generally easier to get help if you spell things out like "crossover" and "transmission line speaker" (I think that's what you meant by "TL").  I'm not sure what problems you are trying to solve with tri-amping and fourth order crossover filters.  Nor do I know if the fourth order filters are analog or DSP in nature, implemented at line level or post-amplifier within the speakers.

The bass improvement was definitely NOT worth the degradation.

As suggested I set up the "FLAT" first and then the desired bass correction. Even the "FLAT" setting was unacceptable. After the enthusiasm expressed for Camilla her, I had expected better.

Do you have any measurements showing that there was actual degradation, versus perceived degradation?

Good morning! Yes - this is the hat I am using.
It is an analogue XO. And my first foray into DSP.
I do not have any way to
 measure distortion etc. Nor am I trying to solve any problems! This is a system I have been building/refining for 20 odd years and - I am very happy with it! Just looking for a little better bass extension and thought this might be the tailor-able solution that would work
I have been using moode for several years and again , I am more than happy with it! And the AD1868 hat has been a revelation!
Thanks for your response!
