    Thanks, yeah you were seated at almost the sharpest angle. A smaller angle though is the sweet spot. About 15-30 degrees is nice and flat. On-axis has a suck out and top octave rise from the waveguide and too far out obviously the top rolls off and I assume the back wave of the mid is dominant.

    Two nice things I notice with them in my living room is they sound good no matter where I am on the couch. Very wide sweet spot within reason, no head in a vice. They also change very little for being a dipole in regards with distance from the wall behind them. I didn’t mind making them two feet deep as they should have at least that anyway. Right now the back of the box is only 6” from the wall and they sound good and have a large image.

    Good point, thanks, I had thought about that as well. I could have cut them a little bigger to begin with, but the tape is a good suggestion.

    Thanks again! I hope they sound ok.

    Those CSA seem like really well made caps. The leads are long and heavy.

    Yeah there’s a bit of everything in there. I had several different caps in the parts bin and also ordered some to try. I don’t want to start a cap war, but will just say I enjoy trying different caps as a part of fun of the hobby. The black mundorfs are actually electrolytic - in the tweeter circuit (gasp!)

    There are more caps than need be because I bundled caps to get to my value because I used up several I had laying around in conjunction with some new ones.

    Thanks! A camera phone and poor lighting hides things well

    I have them all buttoned up. I still need to put together a final schematic and maybe a final measurement. Not a lot of time though as I have another pair of speakers I’m trying to wrap up as well for MWAF.

    Thanks Bill I look forward to meeting you as well! I’d love to have some pics by you of them, just keep the resolution low to hide all the flaws

    I haven’t jammed on them much with the assembled crossovers so the heat sink hasn’t shown any heat at all. The midrange resistor dumps a lot of power and the 10w I used in voicing got noticeably hot, so I will be curious to see. I could have just used some big 25w cement resistors but wanted the visual of the heat sink to make the crossovers resemble each speaker having a monoblock amp.
