Oh man, I'd love to try one...
On a minor note, the area of a circle is computed (pi * r ^2)
So the surface area of a 4x10 = 4 * 5^2 *3.14 = 314 sq. in
And and 2x12s = 2 * 6^2 * 3.14 = 226 sq. in
In this case, your surface area estimates are roughly proportional to the actuals. But if you're talking 15's, it becomes more important to use the right method, e.g.
1x15 = 7.5^2 * 3.14 = 176 sq. in.
whereas a 2x10 is only 157 sq. in
But IME, surface area is only one small factor. The Ampeg 8x10 has a nice hefty presence, but almost no cut at all.
Sounds like that's NOT the case with the HS410 though...![]()
86 lbs. though ...![]()
Good point. Hah, forgot my math laws then!
Can't wait to try an HS410...
