I have and use my mr835 pro sound reinforcement 3 ways very often.. Recently I lost my bass in one cabinet. After testing both woofers, my conclusion is I lost my bass in my crossover in the one cabinet.. Can this be repaired and by who..I use these for live sound and they have been very reliable to me. I would like to get the crossover repaired... Any help or suggestions would be great.... Bear POint me in the right direction Please.!!!
