Dave, I wanted to tell you the Kartunes didn't sound 'weird' to me at all. The Kartesian had some panache or finesse to the details that others lacked. I was surprised it had such a deep cone profile, but this likely helped in acoustic center alignment.
Eric, I really liked your truckin' speakers. The bass was very good. The widerange was very agile and did quite well.
DaveH, I think the Mark Audio in yours were the most directional of the group, but I really liked the cabinet aesthetics. The woofers were very clean, as was the MA, but in the middle was considerably better on the top end.
Bill, it's amazing you can get that kind of bass sealed out of the 1139. I bet I've used that woofer a dozen times, and never thought a sealed box was worth the model. I've always vented it.
Tim, I liked yours a lot better after your component changes. I do want to point out though that mounting with steel machine screws and nuts is not preferable and will alter your inductance values.
My Markaudio CHP-90 were (nominal) 5" (Sd=85cm2) with 7mm Xmax.
I also had the biggest woofers (10"). I was hoping the BWE (Big Woofer Energy) would help my entry out a little.
It was a great event. Thank you for organizing. Those Kartunes were great given the constraints. Always interesting to see the interesting design approaches people take. Whether non-commerical (everyone but especially Meredith's compression truly omni-directional driver), or the Walsh Ohm Model 5.

Thank you all for bringing them!

Surprised no one used anything bigger than, what, 4"...4.5"?
Looking forward to next year👍🏻

I’m a fan of the MA CHP-90 paper+ cone. Most broad / full rangers have but a fraction of it’s Xmax and it’s frequency extension.
Hmm, "not the size, it's the motion"

I put the design link for the R2D2s in this thread: https://diy.midwestaudio.club/discussion/2999/r2d2-tweeterectomy-theme-entry/p1?new=1
