Yeah...the 340's are even more efficient.

When we had the budget speaker listening session out here earlier in the year, I remember reading the efficiency rating for the M22's and the CBM-170's, and expecting the M22's to sound louder. It was not the case. I do not remember how much louder 170's were, but it was not a minuscule amount.

Will...the specs you have seen in reviews, were they manufacturer specs or third party? I know the specs that Ascend lists for their products are as measured by a third party.
