TS parameters when changing Flux Density
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.
