thank you for plans! I've just realized that my 2226 are 16 Ohm version (no H ones) Could the Pi 4 be done with them? Do you have by any chance a crossover for this "J" version of 2226?

Sorry, no. The design requires the 8Ω 2226H.
Some people have reported using the 2226J in a modified design, but I have not seen measurements of such a speaker, nor have I made any measurements myself. So I don't know how much of a change there is.
People that modify the crossover for a 2226J double the inductor values and half the capacitor values in the woofer circuit. They also attenuate the tweeter 3dB to match the voltage sensitivity of the 2226J. This is done by changing R1/R2 values as shown in the chart below:

Hello!
I'd like a set of 4Pi plans please. Got two 2226H drivers and looking for something to build. Perhaps with 4 channels and a 2x4 MiniDSP I can forego the crossover.
I've not heard the HTM-10's. There are a number of threads on other forums that go into detail about the DIYSG speakers and their designers seem well spoken and diligent. There are many folks that have built them that like them.
Thing is, you already have the 2226h woofers. These aren't the entry level woofers for the 4 pi's but the full blown upgrade woofer. They are also the single most expensive part in the 4 pi build - about $1000 for a brand new pair. It's a great woofer even when you have to buy them retail but you already have them ... IMHO it'd kinda be a shame to ignore them.
