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.
