I carry with the thought of building a Zen-biamping version, driving two-way loudspeakers. Active crossover frequency is around 3000Hz. Since I will go unbalanced, I thought of a ZenV4 for the low-mid frequency range.
For the tweeter, I asume, no feedback would be the best choice, since power plays only a subordinate role in that range of frequency.
Any suggestions for the high freq range?
You might consider the F2 clone schematics which haveappeared on this forum.
Thank you for the suggestion Mr. Pass.
The topology of the firstwatt amps is indeed very interesting, but leads me to another (maybe stupid) question:
How could I match an active current source amp like the f2 clone to a gain 4dB lower than the zen4 (low-mid speakers are 94dB, tweeter is 98dB)? Measuring the input and output voltages across a dummy load doesn't make much sense here :confused:
