Hey Alaska,

I don't understand what you mean by losing 80wpc?

When you drive more than 2 speakers, isn't the theoretical net Spl increase on more channels driven making more efficient use of the total watts available in each circumstance? Since the first few watts do most of the work I understand.

Even if it means only driving each channel with a max of 80w x7 vs 160w x 2?

The net output is much increased, no?
