Agreed @WellBurnTheSky, speakers are to amps, what pickups are to guitars imo. They have the final say in how an amp sounds, just like pickups do for guitars. Of course everything has an impact on tone, but some things are so minuscule in affecting said tone, that I don’t concern myself with them too much. I was referring to what a cabinet is made from, ie; solid wood, plywood, MDF, etc. To me these materials are not nearly as crucial as the speakers.
