Re: Active Crossover
Good story. You're right that there are no external adjustment knobs on this crossover. You set crossover frequencies by changing components. I suppose you could make it switch selectable between a few set frequencies though. That's one thing about bui...

Allan,On the tweeters let me say that I really like the Pt2 planars versus the small domes eventhough you don't have that much array gain. If you have to increase the sensitivity, then wire them for a lower impedance (a 4 ohms array would yield 3 dB more...
