need help with impedance on SF power 2


I just get a Sonic Frontier power 2 and Genesis APM-1. On the manu, APM-1 impedance is 4 ohms and I am not sure what is the normal impedance for power 2. Is all SF power amp @ 8 ohms. I read on the manu said I have to make sure impedance match with speaker. What effect if I have 8 ohms on the amp and 4 ohms on the speaker? I felt like I need to turn up the volume quite high in order to get a good sound level. BTW, the APM-1 is 90db sensitivity.

The power will not drop, and the amp will work easier set at 4 ohms, thereby prolonging the life of your tubes.
