Neil,

I typically use Mills 12 watts non-inductive resistors for most speakers. Only for higher power speakers would I use multiple resistors to increase the power handling.

On coils I typically use 14 to 16 gauge air cored units for such individual BSC cricuits. For tight packaging I might use laminated core inductors for the most inductance in the smallest package.

Jim

Are you sure ?

Neither the Spendor speakers I use now, nor the B&W speakers I used previously have any such compensation. They just have standard cross-over networks, with a small amount of impedance compensation, to allow for the rising voice coil impedance of each driver.

Neither of these speakers sounds particularly bass-light, quite the reverse in fact !

Could also be compensated for in the tuning of the cabinet, if not in the crossover circuit. It all comprises a system, and manufacturers will be doing in-room measurements, multiple prototypes, etc etc, to make the speaker sound the way they want it to.
