Given that it is 8 ohm speaker….Y
So, I guess I understand that now, nominal impedance is just a number. Highly questionable, I guess that is so with sensitivity ratings. Different frequencies produce different amounts of energy, so that could be all over the map in reality.
But if 8 ohms is optimum then why are there so many 4-ohm speakers? I put together a DIY speaker a while back and I was able to use all 8-ohm speakers. So, the drivers are out there.
And companies like Rockport, Wilson, etc. claim to make their own drivers, but they design them with lower ohms. Why?
