My tired old brain is still struggling to understand how this works but it may well function, I just don't understand how you would appreciate any kind of advantage. I'll be surprised if you do, as you are not really adding anything to the present system.
Have you heard someone else's Klipschorns that demonstrated better bass? What was driving theirs? Is it deeper bass that you are looking for? Klipschorns are known for being very effiicient and it sounds like you have more than enough power to drive them to their potential. I just don't know if they have the bass that you are looking for. I think I read 33hz as their bottom end. Does that sound right? Maybe I loooked at the wrong ones, not sure but if that's the bottom, I don't think any rewiring or re-amping will do it.
