Those are beautiful. Did you ever end up posting the file on thingiverse? Considering tweeters for my next build and really feeling these.
Yes, 2 ways only.

A brief description of my sound system:
Direct drive turntable and moving coil cartridge for vinyl´s " mint" and MM for others, RIAA tube phono pre-amplifier, Push Pull power amplifier also tube with 38 watts / channel in Ultralinear mode or 28 watts / channel in Triode mode.
I use the high resolution DAC for streaming and / or playing CDs
The amplifier feeds the full range of frequencies to the high-efficiency speakers, it is a Troels Gravesen design with a double horn output to the floor, and direct radiation to the front - with tweeter and midwoofer - and to the rear with two 10-inch drivers each cabinet.
To cover the sub-frequencies I use a 450 watt / channel PA amplifier that feed two sealed and corner subwoofers PA 18 ", the left one is in the same environment of the photograph (excuse the quality), and the right one can be seen in the adjoining environment.

This DIY horn system is the culmination of 45 yrs. of speaker building and commercial speaker ownership. I will forever be grateful to Dr. Bruce Edgar for helping me with the design of this horn system.
So, here is my system description:
Speaker system: This is per channel.
Tweeter: TAD ET-703 ( beryllium) which covers 10khz. to 45KHz. I made the aluminum horn that is powder coated red.
Upper Mid range driver: Custom field coil driver made by Jeffrey Jackson and Dave Slagle using JBL 3" beryllium diaphragm. Covers 5kz. to 1 khz.
Upper Mid range horn: Custom made by me using layers of baltic birch plywood in a 1000hz tractrix curve. Covers
Low Mid range driver; Classic Audio field coil driver with Tru-extent 4" beryllium diaphragm. Covers 450hz. to 5khz.
Low Mid range Horn: Sierrra Brooks 250 hz. mahogany tractrix curve.
Mid Bass drivers: 2 Altec 515B's 16 Ohm drivers in parallel per horn. Covers 60hz. to 450hz.
Mid Bass horn: Hypex curve with double 10 1/4" square throats.
Subwoofer Drivers: 2 TC Sounds LMS 5400's 18" drivers in 9.5 cu. ft. sealed cabinet using dual opposed configuration.
There are 4 Lambda variable powers supplies ( 0 to 20 volts ) set at 15 volts to power the 4 field coil drivers.
The horn speaker crossovers are all 6db passive using mostly Duelund capacitors and 8 AWG Solen air core inductors along with Path power resistors.
Electronic components:
Preamplifier: Cary SLP-05 modified by removing all electrolytic caps from the power supply and replaced by film capacitors.
Amplifiers: For the horns-- Electra-Print custom 845 mono blocks with ELROG 845 output tubes.
For the subwoofers-- Pair of Crown I-Tech 5000hd amps strapped as mono blocks EQ'd flat from 12hz. to 60hz with 48 db filter slope.

Noted Joe's system.....i simply don't have the room/space for horns.
I do know what a musical delight a proper horn system can bring. Breathaking ! This will cost you a lot of time/money/effort to get everything right as a hornsystem is ruthless: it simply will show all defaults in the complete system (the horn-system itself included). But if you get it right: bliss.
Again: i do not have that space which is a requirement for a proper horn system. Joe has....and makes optimal use of it !
My speaker system is based on open baffles (woofer) and K-tubes (mid & highs). Of course both systems react to the acoustical environment but they do function in smaller spaces.
My system:
Speakers (DIY):
XO (partly DIY)
Analogue source:
Digital source:
Preamp (DIY):
Repeater triode in mustage
Tube options: PT8, 4019A, 3A-107a, 101F, etc....any 4V/0,25A repeater triode will do
External 63 steps volume control
Poweramps (DIY):
All in all a well sounding set even in this confined place.
Different tubes can do a lot in a system; always on the lookout for interesting ideas. It is obvious i do not go for the standard/commercial ones....
Happy listening
Regards,
Reinout

My system:
Speakers (DIY):
- von Langa A1000 15" woofer (in open baffle; up to 500 Hz)
- von Langa AD-5110 2" compression driver (with K-tube; 500 Hz ~ 4250 Hz)
- von Langa A4000 1" compression driver (with K-tube; from 4250 Hz upwards)
XO (partly DIY)
- active analogue divided by a PAP-C1 (modified power supply) between woofer and mid/highs.
- passive divided between mid and highs
Analogue source:
- Caeles turntable (heavily modified), air bearing / air flotation/isolation (400 kgs affair)
- Rigid Float tonearm
- Holistic Audio HA103SEL MC cartridge
- Silvercore Phono 1 RIAA
Digital source:
- Bel Canto CD2 cd-transport
- DIY DAC (TDA1541 NOS; no active output stage - just trannies)
Preamp (DIY):
Repeater triode in mustage
Tube options: PT8, 4019A, 3A-107a, 101F, etc....any 4V/0,25A repeater triode will do
External 63 steps volume control
Poweramps (DIY):
- woofer-amp: 35TG in SE-parafeed. 8Watt
- mid-amp: 6C45 in PP-parafeed. 2,6 Watt
- tweeter-amp: 4P1L - ED111 in parafeed; 0,7 Watt. Instead of the 4P1L the Ec or AC101 can be used; Instead of the ED111 the ML6/VT105 or 12B4 or 6S4 can be used.
All in all a well sounding set even in this confined place.

Both of the above systems show how different (and interesting !) this audio-hobby can be.
Totally different solutions but with the same goal: correct sound/music reproduction.
What "correct sound/music reproduction" is, is already difficult to answer but good enough for me to explore.....
The path/search of audio-nirvana never stops.
Enjoy your music/set !

Congratulations, great equipment,
I would only recommend improving the TT, surely it must have a lot of wow and flutter !
What do we have here?
Left to right:
Luxman PD264, Vincent phono stage PSU, Townsend Elite Rock mkII, Denafrips Ares II with DIY Akitika MM phon on top of that is the Vincent PHO-8 set to MC.
Copland CSA29 integrated with DIY B1 mesmerize Pre and SB Touch.
Vincent CD-S4
i7 laptop.
Standmounts are the Lenehan LK1 kit on custom stands and the sun is a 4ft tall TL design with 10" Peerless XLS driver and 250 watt plate amp.
