RX8 does have too much bass IMO. As for the CM8, RX6, and X32, all 3 are rank at the top in that price range. They are all outstanding speakers and give you great value for money. However, IMO, the X32 is the standout. The X32 is the best balanced of all 3. It will sound the most "real" and have the most accurate tonal balance of the 3. It is an exceptionally good speaker. With that said, you can't go wrong with any of them, but I'd rank them for my own preference like this: X32, RX6, CM8, RX8
