Wireless Indoor Outdoor Speakers

Will multiple wireless outdoor speakers work off of one transmitter if they are both the same model?

Specifically, the Sharper Image Wireless Indoor/Outdoor Speaker with Audio Transmitter, but info on any other make will help as well. I need more than one speaker, but only have one output.

1. It is highly likely that it will work. They are probably 900Mhz analog, and a simple CH1-2-3 switch, all factory set to particular frequencies.
