I’m sure there’s nothing really special about expensive/absurdly expensive speakers except careful design and a lot of trial and error. I’m not the type to think there’s “magic” there. I obviously took apart my speakers which were about 6-7k new. Nothing special except very solid cabinets with internal bracing, impedance-equalized (rather complex) XO, no ultra fancy unobtanium coils or caps with bamboo dielectric. Hell there are coils with ferrite cores in it. The only problem is time and a place to work. I’m in Europe in a small apartment by US standards. I did turn my place into a workshop before but I now value comfort more. Oh and the fact that one needs to accept possible failure. The fact that I mentioned digital XO and active amplifiication is that you can go wrong with passive XOs and it’s a lot of work to tweak them. They can mess up phasing so the speakers can sound flat or weird spatially. Ask me how I know.

Now that shape is something new to me.

Can you share details about the project? I looked up those drivers and holy shit they look on another level compared to what I used to know when I was into audio DIY.

I build a few speakers before. IMO it’s a hit and miss thing, I’d personally be very cautious about spending a lot on top of the range drivers for DIY. My experience is that used speakers beat DIY at price/value and that’s disregarding the effort and the fact that you can listen before buying. I have this project in the back of my mind, something with extreme quality drivers and active amplification/digital XO but that would be many thousands of euros in parts for a questionable goal. I’m not a snob, if someone told be you can reach that level of sound quality with this specific DIY project I’\d go for it without thinking twice about it but oh well…
