I recently purchased a Clark Synthesis Tactile Monitor to mount to the underside of my drum throne. It needs a amplifier. Clark Sysnthesis recommends the Macro Tech 602, however, I think it might be overkill and over-my-budget. They say that the requirements are 150-250 watts at 4ohms. I am looking at the XLS models as a possibility. I will be using this system for local nightclub shows 2x per week. What should I do?
