Wayne: Now that I have enjoyed my new 2 Pi Towers for nearly a week, I would like to know what the approximate efficiency is with the Eminance Alpha 10-A and Vifa tweeter units. I am looking to establish a baseline for efficiency and sound as I experiment with other designs or listen to other systems.Despite the fact that the 2 Pi towers I recently completed edged very close to crossing the line of the 'wife approval factor' (WAF), she loves the sound, too. I can't get her interested enough in learning how to turn on and operate the system, but I will take any support I can find with my roommate.
