Having very good components in the part of the filter corresponding to the tweeter is highly recommended if you listen to good/very good recordings. Why not change the Audyn red for another? A safe bet is Jantzen Z-Superior.

The increase in cost is offset by changing the Viborg binding posts for ETI (or equivalent) if you have not bought it yet

I also have option of using BP-603 Viborg pure copper posts. Same ones used on Warp-1 amp. But I think the Viborgs I have now are just fine. Copper plated brass.
The ETI’s look nice though.
Production crossover will use custom manufactured MKP film cap as well as custom wound inductors. The photo you see uses off the shelf ones and Audyn Q4 is what I use for prototypes.

Final listening test in bedroom setup. Still superb and stunning sound. Love these speakers! Final song played before boxing them up to ship to client is Dire Straights’ Brothers in Arms. Amazing rendition. The weight of the bass and richness of the intro’s pageantry is amazing. The clarity and emotion and visceral feel of the vocals gives me goosebumps. Hugh Dean’s Deltic Class AB amp did the job perfectly here. Simple Amazon Dot as streamer source is not bad at all. The XO voicing is spot on.
I have some great news to announce: Galion Audio, Inc of Canada will be selling these speakers under license. Galion is owned by Thomas Tan (Thomas and Stereo YT channel).
They will have some custom voicing tweaks by Galion and you can see the new crossover designed just for Galion below. The speaker itself will be finished in antique brown stained birch plywood.
Here is the crossover PCB. The capacitors and inductors are all custom wound.
And here is the CNC’d aluminum binding post plate, labeled with laser etching.

The Galion TS Voyager TL speaker will come in a finish similar to this - deep antique brown stained birch with a satin clear coat finish and matte black painted baffle made of birch. Here is an example from the Vanguard:
The speaker will have a magnetically attached black cloth grill. A set of precision cut open cell foam blocks will be provided to obstruct the TL vents to turn the speaker into an aperiodic/sealed alignment for cases where a reduction in the bass extension is desired.

I was skeptical about it but decided to verify for myself what others were saying, without spending a lot of money on the test. I am delighted with the Miflex that I put on my modified KEF Q100 5.25" coaxial. As soon as I put it on a speaker it plays Hotel California theme. The difference compared to the other was enormous no matter how much the channel changed. There were two of us, and we both looked at each other surprised, amazed.
I still can not find a convincing explanation (perhaps even harmonics are created, the loading/unloading is faster...) but I cannot deny the big difference (it is true that my second audio system is highly optimized, at a hardware and software level).
Old pictures.
An idea: the next speakers you design should perhaps use a 6.5/7" woofer, with the tweeter as close as possible and moved to the side. With F3 approximately 38-44 Hz (-3 dB).

I typically won’t design a speaker with a tweeter that’s offset to the side. This does reduce diffraction - but not to the extent that it is a huge difference to the detriment of a look that is not as appealing and manufacturing requires a dedicated left and right channel.
6.5in woofer with close tweeter but not quite 38-43Hz. Statement 100 speaker:

Good to hear from you Diego! Thanks for all the likes.
I have fond memories of making your DLH amp PCB using a Sharpie marker for the acid resist. The amp sounded wonderful - I feel like pulling it out of storage and putting it back on rotation. So simple yet so amazingly great sounding.
