post etf…

ok, dht rob made me do it.

after he poked me at the etf why there is nothing to see on the net concerning my adventures in ultra‐fi, I decided that a blog would be the best solution for an ongoing narrative, with schematics and the occasional photo thrown in.

returning home—as always after an etf—inspired and in a buzz (sleep deprivation), the first thing I did was order a 41hz amp9, to get four channels of class‐d amplification, for treble and bass duty.

secondly, I am right now rebuilding my 360° ring tweeters into a half‐spheres. 15 tweeters per channel, one is already playing right now…
