So I've been on the quest for a modular cab set up, and right now I'm really considering getting two 1x15s and stacking them. I also want them to be light, which is why I'm looking at Markbass. Does anyone have experience with stacked Markbass 1x15s? I'm looking particularly at the traveler series (I think that's what they're called). Or if you have any recommendations for another stacked 1x15 set up to look at, I'd like to hear it. I don't want it to be too expensive, and I'm using a AMP BH-420.
