Or maybe not...
I found an article from the 1950s on speakers that gave the formula:
W8π = B[squared] * V
Where
W = Gap energy in ergs
B = flux density
V = gap volume in cubic centimeters
Since I recone P15LLs, I have one that's just a basket, so I could measure the gap. I calculated gap volume as 4.89 cubic centimeters. That gave me a flux density of 8.36k Gauss. Of course, that seems somewhat low to me compared to data I've seen on other speakers, but Jensen never seemed that interested in publishing detailed specs on its speakers.
At this point, I give up.
