Hey, I've always played out of one 4 ohm cab but wanna switch to using two for portability. I have an svt 210 I use for practice and love it. Was looking at purchasing a portaflex 210 for $200 thats in great shape. (probably look kinda weird stacked with my 210svt) Would these cabs match?? I know the svt210 has a lower power rating. I heard mixing different speaker sizes isnt the best idea so thats why Im thinking about the portaflex. Would mixing driver sizes also be a decent option?? I play out of an ampeg b2re if it matters.
