Ashly xr22 18db/Octane or 12db/Octane?

Can anyone offer some advice on which better suits for the 4343 bi-amp active crossover:

To the best of my knowledge, the intended xr network for 4343 was 12 db/octane, right?

I'm using currently JBL M552. I've used Ashly XR1001, but M552 sounds better to me.

Your opinion is truly welcome. Thanks.

octane = anti-knock measure used for fuel
octave = range of frequencies

Just sayin'

Personally I like high octane crossovers, keeps my woofers from knocking under power. Better getcha sum!

I would bet that was a auto spell, auto complete word swap. :^)
