I've heard lightwieght cabs sounding good but i honestly think there is something missing. For example I heard two bands play the same venue. One band had a markbass cab the other had a ampeg cab. The ampeg filled things out better. It just filled the room with the the bass without being louder if you know what i mean. I don't know the science behind it. Maybe its the mass of wood resonating i don't know. I'm all for lightweight gear but i think my next cab purchase will have thick plywood construction and non neo speakers. Does anyone share this view?
