What 1x12s for a W/D/W set up...using 3 1x12s

[sparkle**]

I got an empty Bogner cube...Need to figure out the best speaker for a marshall JMP style 50 watt head....

I am going to use this as a dry sound cab in a W/D/W set up with 2 1x12s....

For my wet cabs I am not sure you "need" to go same or what other options?

Thanks
