I’m just contemplating on where we are right now in the state of speaker cabinets. As the development of small, lightweight class D amplifiers has pretty much eclipsed the the previous generation of solid state amps, speaker configuration has remained the same. 1x 12, 2 x 12 , 4x10. Why haven’t manufacturers attempted full range multi size speaker configurations , such as the Greenboy designs, or something like the Accugroove designs? And with the availability of lightweight efficient power , and an almost limitless assortment of pedal format pre amps, why doesn’t any of the popular manufacturers produce powered cabinets ? I guess what I’m really asking for is for POWERED cabinets. They are the next step in the evolution of bass amplification. Why haven’t they caught on ?
