I've noticed a lot of questions on using non GK speaker cabs with their GK amp heads. All I remember @rag saying is that his cabinets are optimized to work with their amp counterparts. Having said that, I do use my heads with a DNA DNS112 with my GK MB200, or 2 x Eden EX110's with my GK MB500. It's been my goal to sell those cabs and buy appropriate GK cabs. Since the pandemic shipping rates have quadrupled and the market is very slow. No money no gigs. A testament to how great GK amps is that even though I'm not using GK cabs the heads still sound incredible. But everyone has their own preference to equipment.
