My first attemp (Dynaudio D260 + Scanspeak 15W/4531G00)

First time tried to diy speakers, and with the help of Vituix and REW, it was a lot easier. Referring to DYNAUDIO SIRIUS and use first-order crossover, sounds pretty good so far. The actual measured impedance curve seems to be okay. Sharing here seeking for more advice!

I see no real strange things, apart from a seemingly missing baffle step correction, but we would need to know the enclosure dimensions and placement in room for that. Where did you get your measurements from?

This part is only needed when you run a tube amp. Otherwise it is just a power sink, skip it.

The measurement position is the usual listening position. I know that the margin of error may be a bit big. But in the future, I will put this pair of speakers on the bookshelf, and I think the baffle step correction circuit may not be very helpful, so I won't use it for now.
