This upgrade gives you extremely low distortion from the tweeter, better pinpointing, better off axis and power response. And the good old Vifa C17 has a magic warm midrange. So if you want a high end speaker on budget who is a easy load for tube amplifiers etc. Good luck 🙂
PS!
1) you must plug the port with foam or a big sock, or even close it with a plate
2) the 0,68 uF paralell resistor on the tweeter can be removed if the 0,56 mH inductor have high dcr
3) yes, it is a series resistor on the woofers, if you dont beleive it sounds good, please find another project 🤭
4) if your sofa is high, make a 10-20 cm base
5) be careful when you cut in the tweeter opening, use a lot of gaffa tape to mask and protect
6) a little extra damping with f ex bitumen inside doesnt harm
7) have fun 😊
