Does anyone know of a DIY cab that has speakers above 36" (in height, not diameter) or so? Preferably not to exceed 24x24x48. I'm slightly over six feet, and really tired of playing to my ankles and knees. All the while constantly being told that I'm too loud, while I can hardly hear myself. Would an inverted Tuba/Titan work, or something similar? Or would inversion present coupling issues? Definitely want to keep it in the single cab scenario. I would love to hear your ideas, be they good, bad or truly bizarre...Cheers...
