The link worked for me. Very nice documentation. I like the detail you present on the amplifier design. I would like more information on the drivers you are using, and the cabinet size/shape/design.
Do you have plans to do frequency response testing of the final design? Does your electronic system have the flexibility to adjust the crossover filters?
Very nice looking project !

Detailed enclosure description is my next step. I am even considering selling pre-cut pieces as a DIY kit if there is demand for it. I haven't finished the second enclosure yet, but once I do, I plan to find a studio (or a lab) where I can measure frequency response of both speakers together in perfect conditions. The crossover frequency and output levels can be adjusted if you aren't afraid of a little SMT soldering
No, the woofer extends all the way to the floor. The idea is to complement it with an equilized subwoofer to get flat response down to 20 Hz. Once I finish the second speaker and measure - 6dB frequency of the system, I will know where to "cross" the sub.
Great project and documentation! Looking forward to seeing your measurements, listening impressions, and final product pictures. Good luck!
Finished the second speaker. Didn't test it in the lab yet, but sounds really good. Uploaded enclosure schematics and PCB files (gerber + kicad) on my website. Also have some leftover PCBs if anybody wants.
Actually I am interested in a FAST speaker so looking at faital 10" driver that you used a some FullFrange Driver I am 51 yeasr old so cant hear anything above 13K . Can you mention how you made the bass encloser sealed or ported size and what crossover. I have miniDSP 2x4HD did you make a miniDSP file or you have passive crossover. Are you happy with the Bass does it justify for a medium room without needing a subwoofer. whast the F3 you think.
You can find the schematics for the crossover and 3d model for the enclosure on my website (see link sbove). I used sealed enclosure and LR crossovers. Bass response will depend a lot on the room. I only tested a single speaker in a bad setup and it shower F3 around 80Hz. Maybe both speakers together at good listening room you can get 60Hz, which for me is more than enough. But if you goal is to boomblast until the walls crack, then you would need a separate subwoofer at least 15“ (or two 12“).
But for lots of people it's not, so what was the need for the next sentence?
Not everyone who has speakers capable of high SPL means they always use it loud in the same way that everyone who has a Porsche drives everywhere at 150mph, but less than 60Hz is actually useful for a lot of my catalogue.
