Focal mid woofer needed? Sourcing help appreciated

I need a Focal 7K011DBL mid woofer (blown one belongs to a hefty monitor with "Legacy" stamped on the tweeter facia and on the back, no other identifying marks). My understanding is that Focal 7K4211DB is a "drop-in" replacement for this woofer, I'd be interested in this model as an alternative. Thanks, Ben
