TS parameters when changing Flux Density

[f4bok]

Hello

I have 4 Altec 421-8H baskets with 416-8B Cones
I know the TS parameters of the original 416-8B speakers with its Flux Density of 1.1 Tesla
Now, new flux density with 421-8H basket and 416-8B cone is 1.44 Tesla
Is it possible to calculate new TS parameters since we know original parameters and original and new flux density ?
Is New Bl = (1.44/1.1) * Bl(416) ?

Thanks
Bruno

Hi,
I've seen tables of the parameters showing how they vary with electromagnet current.
It's not obvious to me what the relationship is with BL.

Safer to just remeasure the parameters at a few test currents.

Sorry.................wrong forum
I copy it to "loudspeakers"
