Well done.
The box is very likely one of Scot’s sketches.
You can’t expect a 3” to be able to move much air, or go very low. But the A5s/CHN-50 i have heard are outstanding above a certain point.
So now as a second project — a speaker diyer sops at one ;^D
1/ larger FR in larger box to see if sacrifices some potential midTop for more bass and levels
2/ play with subWoofer(s) & use the small boxes as the satelittes above 80-100Hz Really needs multiple amplifiers and Line Level XOs
3/ use the title ones as midTweeters and add helper woofer(s). Much easier if done actively but XO moves high enuff that a passive becomesesfeasible
Each is a bit different interesting and valid exploration,

Dave whats your opinion on going dual driver with 1.5 way with 3"? Maybe something like this mltl twin, or I am thinking about micro tower style push push and crossing somewhere 200hz.
2 “microTowers” for single 3”/aka Giraffe for CHN-50. Jjust shipped a set of Giraffe, they play above thir weight.

Back at the office.... Axia each in washbasin over simple wooden cube with latex pillow inside. Total immersive realism; free to rock office chair. Could go on desk if secured to frame etc. (Bottom pics show pulled-out drawers to simulate desktop; how I'm listening near-field right now can't stop.) Arrange tweeter-reflector to bounce toward mid-field seating area, or LX if far-field. Frequency response essentially flat 100-10khz, time- and phase-aligned, wide-even-dispersion virtual point-source.
Thanks for the idea -- I'm the boss but shut the drawer quick when they come in!
I'm listening to Pierre Rampal and Claude Bolling playing "Sentimentale" right in front of me, for the first time -- a recording I had played hundreds of times since freshman college. To me, a new level of fidelity that money couldn't buy -- despite the drivers costing me $100 -- I had to invent it.
Now I'm listening front-row to a college favorite, Julie Su (Su Rui, she made a movie ~1983 Taiwan's version of Coal Miner's Daughter)... standing onstage with band all-around/behind her. Uncanny. Paranormal. Moved to tears.

Just finished a pair CGR dFonken125's. These are part of a birthday present for my daughter; the other parts being an H2 V2 preamp and ACA monoblocks. Sound great... could use some bass assist, but my point of reference are FrugelHorns, which have good bass extension. A bit of EQ helps, and will probably be fine for my daughter.
Thanks planet10 for the free plans!

CGR. looks like a millSize, mFonken125, nice job.
Easy (mostly) to do tweaks that help the FFxx5wk (some of them good on FExxx too): https://www.diyaudio.com/community/threads/opinions-on-mods-to-ff85wk.365756/post-6480912

The lacewood board I had for the front baffles was a little too narrow for a true GCR so I tweaked the other dimensions a bit to maintain the internal volume.
Presenting the "Omniglassball"
A 3D printed omnidirectional desktop speaker, assisted by a 5" underdesk subwoofer.
Driver: Tangband W3-2141
Enclosure: Conical 2.7L bass reflex with chamfered 3D printed in black PLA
Dumping: Gyroid infill @8%, serving as dumping and walls reinforcement at the same time
Deflector: 2" solid glass ball attached to the fixed original phase plug.

Thanks Dave! A pleasure to hear this comment from you!
Yes, it's raw PLA, using the option fuzzy skin on the slicer. Some tests and i have found a really nice configuration that hide the seams and gives like a natural finish to it.
I believe it was 0.3mm x 0.3mm on the fuzzy, using a 0.6mm nozzle with 0.8mm wide wall (4 walls, last one fuzzy).
Desktop speakers with MarkAudio CHP-70.
No real need. I've built them because I can.
