Congratulation Cooky, this is an amazing design!
After lots of listening and playing about may finally settle on 2nd order Butterworth slopes @800hz(600/1048hz) with 110mm delay on bass driver.
Need to get some measurements done but my ears are saying smooth integrated sound with best imaging..
This was a really great project .
Do you still have these ?
( If so ), do they outperform ( imaging wise ) your other K9800 project ?

Used 2206s as a replacement for the 2214s in a pair of 4425s. Split the passive crossover into separates. Disconnected one end of the LF inductor on the existing xover. Used a "sub-Bessel" second order with an Erse iron core low resistance inductor for the 2206s. Holy crap! What a difference in these speakers. Yep. Snappy base drums and rimshots, not to mention a really good midrange, much improved over stock boxes. Bumped these little monitors to the next league. Left the cabinet tuning the same, approx. 40 Hz. Need to do a little write up with some photos. 2206s are a serious upgrade to the 2214s that were stock. I can't believe how easy this was.

Oh, and by the way Cooky, really snazzy looking cabinets! I feel a want for those! Really cool.
Yes I still use them everyday. They present a considerably smaller but sharper/more pinpoint and deeper stereo image than the larger K2 types.
By smaller I mean individual components within the soundstage are sonically 'smaller' unlike the somewhat larger-than-life delivery of the K2 presentation.
I did play with rotating the H9800 horns and the imaging did become more focused by I lost something too-they oddly became less satisfying somehow(lord knows why) so they stay as they are. Thanks for the nice compliments guys.
Thanks for those observations!
They are quite intriguing .
Without being able to reference them to some polar plots, one is left to muse as to their involvement to listener "satisfaction" .
Maybe the 90x60 nominal coverage of the 4338 horn ( as mentioned by 4313B ) versus the 90x40 coverage of the H9800 ( both on end of course ) played a role in your level of satisfaction .
- The 60x90 would of course have more room involvement ( giving a more spacious sound-stage ) .

PS ; I would love to see some polar plots of the H4338 ( or an actual Array horn for that matter ) / I don't think anyone has ever published them. Anyone ??
Cooky
in another thread I was asking about the advisability of mounting a 1400 Array horn in an OB (for aesthetic reasons) and someone pointed me to this thread. That’s a great implementation. Can I ask how you mounted / fixed the horns in place?
