hey everyone. i was wondering if any of you have tried this combination. i'm in the market right to purchase two greenbacks - pretty sure i'm going with the heritage series - and wanted to get some feedback about this particular combo. in particular, i've heard it's good to run the g12m's in a closed back cab in order to augment the bass response, and i've heard also that port city wave cabs do augment bass response though not a traditional closed back cab. so does the port city cab "take care" of the g12m's thinner bass response?
