I needed a speaker system for my personal studio to listen to and play along (rehearse) with program material at high volumes, but I wanted something much better than live PA speakers. The legacy Cerwin Vega Re30's did not disappoint. They are VERY loud, but also very clear with plenty of bass response. I use two-pair of these driven by two Rockville RPA9 pro audio amplifiers, with the signal compressed, limited, and equalized with a Behringer DEX2496. I also have the (old) crossover capacitors inside of them replaced with good Dayton Audio film-polypropylene caps.
