Maybe one of you audio wizards can offer some help. I want to remove the stock tweeter from a CS350 center channel speaker (8 ohm) and replace it with a Vifa XT like the one in the LSiC (4 ohm). Can I put a 4 ohm resister in series with the tweeter? If so, is there a voltage or anything else that also has to be considered? Would it make sense to just get a second crossover for the Vifa and isolate the original tweeter wires or do you have a better idea?
