The "JCN-JX1" Mosfet amplifier

😀👍 I like them a lot - at this speakers all fell in place with the 2nd version of the crossover. Even the Beryllium version of the tweeter didn‘t sound so well integrated as the fabric version, so I switched back to the fabric and the Beryllium will be used in a standmount speaker with the 15WU.

Very cool! I am just starting to wrap my head around some facids of speaker design. It is a complicated subject... Fabric tweeters do seem like the would cooperate better than some of the more exotic materials. I have an AST which comes with it's benifits but some drawbacks as well.

The 2-way standmount could be an imaging monster. Have you given thought into a curved baffle or cabinet in general? I know this is getting off topic. 😶
 
Hello,

a little update: Prototype with 16 Mosfets / Channel (4 per Quadrant) works very well. A version without Servo and manual trimming. Seems to be stable.
The user feed it with a parasound preamp by XLR and prefers the version without buffer.

So I work at external input boards to play with different buffers. I also like to try an „Super buffer“ inspired by the Borbeley Version.
