The typical male voice frequency is between 85 and 1555 Hz. A really deep male voce like James Earl Jones aka Darth Vader, could be even lower. If you set your crossover to 100 Hz, which you might be temped to do with the M22's, you would get voice out of your sub. This will make sub placement even more critical.
