I would need to see the impedance curves for both the 15s and the 8" speakers.
Assuming the nominal impedances, 8 ohms in parallel with 4 ohms (from 80Hz down) is 2.67 ohms.
That's probably not the case. Again, you need to look at the impedance curves of the drivers you're using.
The 8" speaker might have a high impedance below 80Hz and the load seen by the tube amp might be around 4 ohms at those frequencies.
4 ohms connected to the 8 ohm tap will show the 300b one half the normal impedance and that will increase the power and increase the distortion.
