Default Alpha 15A Upgrade in OB

Have been running Alpha 15As in biamped OB for a few years. Wondering if there is a reasonable 12 or 15" upgrade to these. TIA

I have questions:
What's your Crossover point?
Are you looking for a Specific Qts?
What's your Budget?
What don't you like about the Alpha 15's?

>>What's your Crossover point?
Currently 200 Hz

>>Are you looking for a Specific Qts?
Seems you want around 1.0 or greater in OB

>>What's your Budget?
$300-400 pair max?

>>What don't you like about the Alpha 15's?
They don't seem to have the best definition but I might just need more power and a lower xover point.

Hi, I don't think it's necessary to exchange the woofer, rather if, then design philosophy, imo. This is the response difference between a sealed and OB driver loading, having in mind that I haven't simmed additional stuffing that would have reduced the Fb peaking. In case that your XO filter isn't optimized, you'd for sure note something wasn't as good as it might have been. Baffle step is factored in.
