He is not unhappy with his current setup so no need to spend money on new speakers and i know the M5 is hp and if he is using a sub then he has no need for them. Your advocating for more bass in one breath then telling him 2 500's are too much in the next. If he is looking for an excuse to buy new stuff thats fine but he doesnt need to replace perfectly good speakers. Different doesnot translate to better.
