I have a question to all of you, who have some SFI experience:
does it make sense to make a driver out of three SFI's - 2 of the 8 ohm tweeters, respective their magnets with the holes, plus the diaphragma of the 32 ohm dipole?
The reason that I ask is that the 8 ohm 2 in 1 SFI that I made is the "nearest headphone to the electostats" in terms of transparency and clarity of all other headphones that I listened so far. but they lack in bass too much. The reason for their precision could be the stronger magnets - they have also a higher sensitivity as tweeters than the 32 ohm types (which have smaller and weaker magnets). this results in a better control of the diaphragma.
my idea is that the 32 ohm diaphragma could exert a higher dynamic force against the strong magnets and get more extention = bass.
any comments are welcome!
