How do you get a 250 lbs Speaker on an SP-101?

Here's my invention of the day: Speaker jacks. Remote controlled motorized platforms that slide under one's speakers. The remote should have L/R speaker, raise/lower and a joystick. When raised, one would be able move each speaker backward and forward, left and right, adjust toe in. All from the listening chair. When the optimum location is found, simply lower the speakers onto their spikes. Probably would need to raise the chair to keep the height consistant while doing this. Most people would not use these often enough to justify the high cost but dealers could rent or loan them out.
