Parts Express usually matches Dayton's numbers.

But, I think Parts Express accidentally type 1.70 when they meant to type 0.71.

To make sure, I ran the numbers for both the 4 Ohm Reference HF and the 8 Ohm.

I am confident that the 4Ohm Reference HF is built for a smaller volume box than the 8 Ohm.

This leads me to believe that the Dayton website has the correct numbers.
