I forgot to update this thread to show that I listened to this new XSD and it sounds great. Here is video of mono speaker played with Warp-1 Class D amp.
Measurements of the XO response shows pretty consistent with previous speaker - there is a small peak in the woofer output near the XO frequency. Probably driver to driver variability. The mid range also has a little more structure at the top end.
But overall, the sound is very lively and dynamic. Distortion is low and speaker is clean sounding. There is a distortion peak around 370Hz but level is low - it’s probably related to a cone breakup mode for this batch of drivers.
I gave the speaker a test tone (sine) at 370Hz and monitored the FFT spectrum and it shows dominant even order harmonics and circa 0.11% THD for 2.0Vrms. The even harmonics are at least pleasant sounding vs odd order.

"X", What is the approximate box shipping size? I live within 100 miles of Leoanard, TX and would consider a direct pickup with my little car - if possible.As promised, the packing is progressing nicely but is a lot of work. You can see how carefully the pieces are packed in foam and strapping and then a nice box and then strapped on the outside.

Folks should be receiving tracking numbers soon.
Yes I think so. Let me check. But we can get an order set cut if there was interest.Are these still available with walnut?

Where would you put the second set? That’s a nice testament when someone wants to build a second set.I mentioned the other day I had picked up on sale, another pair of the midranges "just in case" right? I just did the same with the tweeter. I'm fooling myself, I'm getting ready to build another set aren't I? Oh brother....

@dawa : what was the carrier service you used to ship XSD from USA to EU?
Thanks.
@Quirepace : we sold the last walnut flatpack but can make more if you are serious.
