I parelle the RIFA 1uF with NEC paper in oil which I got form surplus.
This greatly improves sound details.
These PIO caps were obtained when I was in colledge , almost 20 years ago!!
Hope they doesn't contain any PCB!!!

The crossover circuit is simply a 1st order high pass filter by means of one 1uF in series and followed by an attenuator.

After long wait, finally it's here.
The FOSTEX T-900A super tweeter.
See the extreme small horn mouth , it is a super tweeter indeed.
Which means you better use a higher crossover point than nromal tweeter.
Adding T-900A , surely improve top end of FE-208 ESigma.
But still lacking bass punch, after more break in ,maybe it will be changed.
