8 or 15 ohm

genalex · 6th October 2006, 02:06 PM

I want to buy a lowther PM4a but which impedance is better, 8 or 15 ohm?

My amplifier can is 300B powered and with both 8 and 16 ohms out.

Someone told me 15 ohm is better but what is the reason behind?

Higher impedance will have less losses in the cables etc, but between 8 and 16 ohms the difference is negligible.
