Dear Troels Gravesen!
Unfortunately, I don't speak much English, so I will communicate with the help of an interpreter.
You probably know, there is a war going on in Ukraine right now, and your country is VERY helpful in our fight against Russia. Thank you to your Government and your People!!!
I had to leave, hopefully temporarily, with my daughter's family in Cyprus. And now for 2 years we are in Paphos, but my passion for sound is for life, it's my favorite job and hobby! There is a lot of time now and I analyze my projects, I try, how to make an upgrade, how to improve the sound?
In your project I liked the choice of speakers, docking HF and MF, but I am a lover of deep bass, low-frequency link made a separate(biamping) used woofer amplifier D-class with EMOS - Electro mechanical feedback  (this is when the cone sensor on the cone, associated with the amplifier). Developed by my colleague. SB Acoustics 34NRX75-6 head. In comparison with your variant loses, probably, in correctness of bass/midbass, speed, but wins on depth and distortions, linearity  of  frecuency  responce  in the low-frequency range. I have the simplest device...photo of the frecuence responce of the bass range in 1m. Well and different photos of my system....test disks.
Best regards, Serhii
