- Good One Dave !

- But no , I'd say it's a matter of making a comparison between the BL figures when looking at the so called 8 ohm versions vs the nominal 16 ohm types . Just about always, the 8 ohm diaphragms have more electromotive force after a per unit normalization . It stands to reason that these higher BL types will also have more modal breakup issues and thus measure slightly different .

- In the SR world up here in central Canada , it's long been a held opinion among a certain older crowd ( defined as over 55 yr , as of 2006 ) that JBLs' 16 ohm type diaphragms sounded "smoother" / across the board for the different models ( FWIW ) . Why ? Think of the BL differences that Giskard ( & others ) like to chew on when someone creates a hybrid ( franken -) woofer using 2235H cone kits in an overmagged core assembly.
- That same focus can be shifted onto diaphragms when they are put into none standard motors ( especially when the motor has a different gauss level , ie giving a non-standard BL coefficient ) .
- A lot of these issues can be explained as what's the best performing balance of FR vs "sound" ( made between a diaphragms mass and the BL that indicates the strength of the motive forces ).
