Let me too add to the Max (P-Trap) Potter eulogy and with sincere condolences to his son, daughter and grandchildren of which he was so proud.
Simply, Max was my friend. Our friendship started some 20 years ago after I wrote a letter to "Speaker Builder" about the K-Horn cross-over. Both Max and Jerry Hunter replied. Jerry with a schematic of a more current cross-over and Max with a phone call that started our 20 year friendship. .Based upon his recommendation, I immediately rebuilt my K-Horn crossovers incorporating his P-Trap. What an improvement! That phone call was the first in many, many LONG Saturday morning calls that increased my audio knowledge exponentially.
Because of his afore mentioned relation with ALK, I was an early tester of the TracHorn and Extreme Slope crossover, modifying both a pair of La Scalas and K-Horns. The speakers I use today have the ALK mid and high frequency configuration that evolved due to Max and the work of ALK. The vintage Klipsch community has lost a true pioneer and valuable contributor to our hobby/passion.
I was fortunate enough to have Max as a guest in my house for extended audio listening and my wife (who Max dubbed "Miss Golden Ears") and I also visited Charlotte and him at their home in Kerrville; both extremely kind and gracious people.
If you have internet access where you are Max, we miss you but take solace in the fact that I'm sure the audio is Heavenly.
Oh yes, one other thing..... Max is responsible for my Forum name "******-Bob".
