Infinity RS-IIIa Several owners ago, they built these crossovers. Any idea what they were trying to achieve? I would think Infinity put at least some cursory investigation into the crossover when they built the speaker. Also looks like they removed the zeners protecting the tweeter. It will cost me a bit, but I'm thinking of rebuilding them with the factory specs. I could pass them on since I have a pair of RS-II that could also use some refreshing, and there's only so much room for floor-standers.
