replacing one 8ohm sub with two 4ohm

I recently blew my 18" sub and am looking to replace it. I was coming up with a rather waffly question and decided to cook it down a little instead.
I have an EPQ2000 amp(2 x 1000 - 4ohm or 1 x 2000 8ohm)
Should I replace the old sub with:
Option A - Fane Colossus 18XB 8 ohm(99db)
Option B - 2 x Fane Colossus 18XB 4 ohm(99db) (double the budget but double the fun?)
or Option C - Fane Colossus Prime 18XB 8 ohm(100db) (25% more than option A but i get an extra db)

Cheers

What driver and how did it fail? Thermal, mechanical, both?

Option B will have the most output by quite a bit and should be relatively bulletproof.

or Option C - Fane Colossus Prime 18XB 8 ohm(100db) (25% more than option A but i get an extra db) Cheers
No you probably won't, power compression will soak that up and below 50hz output potential is determined by driver excusrion capability, the Prime has more of this but also has slightly lower efficiency so I predict a wash.

It was both. I didn't notice the tear in the surround though until I removed it from the cabinet.

I like the sound of bulletproof, and lots of output 😀

Good to know that it isn't worth the extra coin in that case.
