Hello Wayne,
I lost my plans for the 2Pi.
Is it possible to send the plan again?
Thank you very much and best wishes from Germany.
Frank

Yes, we used the DX25TG09-04 before the current DX25TG59-04. And before that, we used the DX25TG05-04.
To be honest, the whole reason we use a 4Ω tweeter is to get the voltage sensitivity up to match the midwoofer. Not many dome tweeters are sensitive enough to "keep up," so we "cheat" by using a 4Ω part.
At 2.83v, the midwoofer gets one watt but the tweeter gets two. So even though the tweeter is rated 90dB/W/M, it's getting 2 watts, so that increases SPL by 3dB. Said another way, it's 93dB/2.83v/M. That's still a couple dB lower than the midwoofer, but it's a pretty good match and it sounds good.
