"Did you take high school physics or are you just stupid?"
High school physics were easy, I got more stupid in college.

Nah, I don't believe you. You might have done some stupid things in college, but you weren't more stupid. :)Back on topic.....we can even put some estimated numbers on the relative differences.
If we assume the excursion capability is equal, the 1.7's are 442 square inches and the 20.7's 800 square inches. (The bass driver determining the overall SPL capability.)
SPL difference equals 20 * log(442/800) meaning the 20.7's can play fully 5db louder than the 1.7's. That's a lot!
And here's a quiz for Potzrebie.....since we assume the sensitivity is the same, how much more power will it require from the amplifier to yield that 5db increase in SPL??Cheers,
Dave.

Did I pass?
Yep. But I knew you knew the answer. :)
IIRC, this exact topic was discussed on this forum about ten years ago. Actually, pretty much every topic has already been discussed years earlier. This is an interesting forum. :)
