Can anyone offer some advice on which better suits for the 4343 bi-amp active crossover:
ashly xr22 18db/octane or 12db/octane?
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.
