F3 suitability

[noviygera]

I have an F3 on loan. A few questions arise:

1. can I safely drive only one channel of the amp (for a/b comparison purposes, L channel my old amp, R channel F3)?
2. how suitable is F3 for 12ohm horn 112db tweeter (bi-amp config, active crossover at 2kHz)?
3. how suitable is F3 for mid+tweeter horns combo (series-passive crossover, 12ohm tweeter, 16ohm midrange)? Midrange will play down to 250Hz.
4. in both above scenarios about how much power will I get from F3?

Thank you,
Herman

1.yes ; ground unused input (plug shorted RCA )
2.it is
3.it is
4.roughly - 50% less

I thought the F3 increases power into higher impedance.
10w into 4ohm
15w into 8 ohms
?? into 12ohms, 16ohms, 25ohms?

Wrong?

according to user manual :

max unclipped output voltage +/-13V , meaning 26Vpp

that's 26/2/1.4142=9.19Vrms

P=Urms^2/Rload
9.19^2/12=7W

so , I was right , roughly

That's the silliest way of comparing two amps, really.
