Every speaker will have an optimal BL product, the field strength in the air gap multiplied by the length of the voice coil wire in the field.
If the BL product is too low, the speaker is electrically not very well

damped (which will result in a woofer with a high Qts). A bump in

frequency response and a level drop in midband efficiency may be the

result. If the BL product is too high, the speaker is electrically

overdamped (Low Qts woofer). A very high midband efficiency, but the

driver starts to roll of early.

An high BL product can be achieved in a number of ways: increase field

strength; or increase wire length in magnetic gap.

The increase in field strength is limited; so some manufacturers use

very thin wire for the voice coil, as such they can achieve a high BL

product with a low field strength (cheap magnet). Or they use an 8 layer

voice coil... needless to say that electrical power handling will

decrease enormously.

Long stroke woofers, having only a part of the voice coil in the air

gap, need a very high field strength to achieve a high BL product. Often

this means a big magnet as well...

Use magnet size as an indication, but as nothing more than that.

Know anything else besides the copy/paste function?
