I've got a Carvin RC210 bass combo. It has a 600w bass head and an attached 210 cab. The cab is rated at 400w - which seems strange, since the head is 600w. Is this 400w the program wattage, peak wattage, or what? Can this cab handle the 600w or should I be looking to replace the 10" speakers with higher wattage speakers? I really like how it sounds, I'm just concerned about damaging the speakers.
