Perhaps this should be obvious to me, but it isn't.
When measuring a speaker on and off axis, say at 1 meter, does one:
A) measure at different angles from the speaker axis along an arc with a radius of 1 meter? In this case, distance of 0degrees, 15degrees, 30degrees measurements are all equal to 1m.
or
B) measure at the intersect of rays oriented at different angles and a line perpendicular to the axis centered at 1 meter on axis? In this case, distance of 0degrees equals 1m, but all other angles have longer measurement distances.
Thanks!

It's A), the rotation point goes through the baffle. Besides that, measurements with different distances can be very useful, i.e. nearfield measurement in the bass if your room is too small to fade out the room influence. Or greater distance, if your speaker is very large and only gives a homogene sound with more distance.
Thanks for the clear responses and suggestion of C), rotating the speakers. Although, I was looking forward to taping all the 'x's on my patio!
