Axiom Home Page Forums General Discussion Technical Questions How can I tell the difference qs4 vs qs8 v3?

I ordered the qs8 v3 and got them in a few weeks ago. THe label on the back says qs8v3 but the ohm says 8 which is the rating for the qs4. Also I measured the woofer on these and I'm not sure where to measure. From the inter diameter of the speaker housing where the foam meets the metal ring I measured 4.25" T#he specs for the qs8 is 5.25" Do I need to measure from the futher most edge of the housing? Or is the woofer measured by the outer edge of the aluminum cone? Im not sure. I see there is a 5 lb difference in the 2 versions maybe I can weigh them to see. I just want to make sure I received the right speakers. Thanks. Oh I called the support line about the ohm difference and they mention it must have been a mix up with the label printer. I am about to pull the trigger on the m80's and I am just anxious to get them installed
