so i decided to take the advice of all you wonderful peoples on the internets and buy a avatar cab.
but what combo of speakers (for the G212H Custom)?
how should they be wired? 4 ohm cab, 8 ohm cab, 16 ohm cab, stereo cab or mono cab?

to make these decisions easy i'll tell you my amp is a Marshall JCM2000 DSL100
it has plugins for the 4ohm, 8ohm, and 16ohm. but i'm wondering what way to have them wired would sound the best. keep in mind that in the future i may want to add another cab onto it.

and what speakers?
i really want some that will work for a large variety of genres. honestly the only ones i dont play are country and deathmetal.
i heard that having 2 different speakers would make it sound better and marry the tones together better.
my combo idea is a Celestion V30 and a Celestion G12T-75

any ideas?
