now this is a motor

look the slugs same diameter as the od of the basket, those are 10s...

is there any point to having three separate magnets?

would it be any different than having just one large magnet that was just as thick?

just wondering.

my guess is its easier to get three 1 inch slugs then one 3 inch slug thus being more cost efficient

your motor is somewhere between the left and middle of these

Diameter of the slugs tends to have more affect on the strength of the field it can generate, while height of the slug(s) tends to affect the potential length of the voice coil. At some point, simply adding more and more slugs does not help BL much, and many times the last slug in a motor is there mostly to allow for rearward clearance of the coil.

A triple stack of slugs compared to a single slug that equals the same size of the triple slugs combined, would offer the same performance potential. Stacks of specific sized slugs are used due to manufacturing reasons, and cost.

No problem, glad to add my 2 cents.

^ exactly.

the 3rd slug for rearward clearence, its many times cheaper that machining a thicker bottom plate...
