David Porter said "I plan to run the power cords for the monitors to a dedicated strip plug that is positioned where I can reach it easily and just power them on and off as needed that way."
David, have you considered that when you throw the power strip's switch you will be sending a surge into the open circuit of your speaker's power amp since you would have to leave the speakers "on" at volume all the time? When you turn on electrical equipment, a quick jolt of electricity goes through the whole system. This can stress the electrical components (capacitors, resisters, etc.) and it may damage speakers if the "pop" that's produced is too loud. The on/off circuitry of most amplifiers is designed to protect the speakers from such a surge; or the start up procedure requires the amp volume be turned down when powering up the amp.
Kevin, have you considered an A/B stereo switch box that has two L/R inputs and one L/R output? By using the A circuit to connect the DP24 monitor out to the speakers through the switch box, toggling to the B circuit will turn off the signal to speakers. T-Rex used to make something along those lines...think it was called "Polyswitch".
