BL is measured in tesla meters, not meters. And what subs are you referring to? BL isn't everything

BL also changes depending on the size of the speaker and it shouldn't be the deciding factor in choosing a speaker

To find a subs motor strength you take the bl square it then divide by the re. When taking t/s specs on a dual 2 if wired in series the bl number will be a lot higher than if taken in parallel but the re in parallel is only 1 rather than 4 so the bl number alone can be very misleading. If A dual 1 and a dual 2 both wired in series show the same bl number the dual 1 will have twice as strong motor force. Weak. Motors tend to do well in sealed boxes and strong motors in ported. As far as actual output though there are a lot more things to take into account.

i know its tesla meters and im just wandering if 1 tesla meter is alot and the gcon vs sa the really only thing i found better about the sa was that is has 1 meter more bl than the gcon besides that the gcon seems like a better sub all around besides i already ordered my gcons i was just wandering how much bl plays a factor obviously it does but is 1 meter a crazy amount more?
