So i cant find an infinity replacement and i dont want to fork out 1k for w7 subs.

what about RE subs or Digital designs?

Will the Dayton Audio RSS315HO-4 12" Reference HO Subwoofer 4 Ohm work fine with this box ?

Unfortunately those Infinity kappa drivers were very poorly made, and just about all have failed.

You can not install different drivers. Every driver has unique T/S parameters and small changes make the design not work.

So picking a new driver means a new design and build.
