hi I'd like to submit this guy hope he hasn't already been posted I did check but might have missed it https://www.diyaudio.com/community/...3-way-full-range-speaker-in-the-world.325521/
savan . I don't know I think it looks pretty solid in all respects I guess we would to listen to it to know for sure
Measurements tells everything. Big speaker, big sound, that's to be expected, but in my opinion it's not well done. My speakers is also huge, around 50L. Those nonlinearities > +-1db in critical region are simply audible even without measurement. My speakers had 3 crossover revisions until I got things at critical 1k-3k region in +-0.5db, I spent more money on crossovers than on boxes+speakers+shipping, the goal was as like on picture, see dbSPL at 1db scale. Obtained in room measurement with Clio, ploted in Xsim.

Whole project for those interested to build.

Upgrade for my ref two way TL speaker , simplification for tweeter crossower, 3 more midbass... etc, d-apolito configuration, when I done I will open thread! Some details https://www.diyaudio.com/community/attachments/2-jpg.1379623/

I don't believe I could hear fluctuations of 1dB.
How did you get the correct FR plots in Xsim with the second woofer not connected and drawn in afterwards?

FRD and ZMA from real inroom measurement while two connected in paralel and mounted in box, imported as a single in xsim...
Your ability to hear smaller variations depends on the overall smoothness, which includes the direct sound and later sounds.
BTW, I wasn't having a go at Savan. I still don't think I could hear it, playing music I mean, not a frequency sweep.
If there was a 1dB bump over 1/2 an octave centred at 1,000Hz, I'm sure I'd need to be able to switch it in and out at will to possibly hear it. I don't think I'd hear it otherwise - say, after soldering in some crossover parts. then re-listening.
Maybe I have ears made of solder. They certainly produce some DIY rosin. 😉

There are forgotten top-of-the-line speakers, some you may not even know existed. You wouldn't believe how smooth the Audax HM170G8 is, I'll honestly tell you that the forgotten Audax HM170G8 single has a deeper and more effective bass than the two SilverFlute basses from my links above, it simply has more dynamics and still maintains linearity. I've had a lot of speakers, I won't blame the manufacturers, various, including the "snake oil" ones, but I will say that for now the Audax is my reference. There is nice simple high end speakers like JA8008-HMQ I must build, for example one variant with HMQ is https://www.humblehomemadehifi.com/download/Humble Homemade Hifi_Plutone.pdf , soo nice design - speaking about simple crossower and linearity, let say dream speaker!

I saw this thread bumped today and definitely think it should be on this list. Based on the unusual and sadly not updated machine-learning crossover software XMachina by xmechanik
I think it was measured impeccably on 🤐 asr - not a site I care for to put it mildly - but it's basically multiple proofs that the unusual circuits produced by the software worked IRL!
