Hi Herman,
Some more details on the Phonic RTA, please? And how did you generate a tone at the x-over point. Did you use a tone generator or Cd, and if so then what was the unit or a reference point of availability for this exercise.
Did the brass rack free up the midrange and top end dramatically? What % would you rate it at.
Have you thought about the Altmann amp ever over the 300B's!
BTW very nice sound! I am envious of the 2 pairs of subs. I thought 3 pairs would be even better but I am glad I read your comments.
