very beautiful, congrats :up:

...i also have a pair of fe108 sigma but has only tried them in a pair of voigt horns ...and also in enclosures which was a copy of gemme audio vivace. fe 108 units can have a bit 'hiss' sound, so it's all about adding folowing filters for these units for better behaviour.

calculation tools can be found here: zobel and bsc
