Ok is it important to have the ohms of all your speakers the same? Now here is a situation, lets say you have 8 ohm main speakers and center, but 6 ohm surrounds. If you had a receiver would you just leave it at 8 ohms? Now if you had seperates would you just worry about the amp supplying the power? So for the 6 ohm speaker have the amp supplying the watts in 6 ohms? BUT what if you have a 5 channel amp at 8 ohms. What would you do?
