Hi. I just read all of your tech pages on you website. Thank you very much. GREAT info! I learned a lot, especially about dipole operation. I have one question. After reading your "Integration of front, and front and rear tweeters to a dipole midrange" article I didn't quite get whether or not the rear firing tweeter should be wired out of phase to the front or if it acted like a dipole either way with the appropriate sized baffle. Thanks again for your insight and great website!
