The "SDA" part of those speakers designs only worked with the cable connected. If you don't use it, you'll have at least 2 drivers per speaker NOT working.
Polk SDA Speaker info needed...
I've got some older Polk SDA 1A dimensional array speakers and people are telling me that the sound is much better when you use the cable that connects the two speakers together. Can anyone varify this and also tell me how I might hook mine up just for a listen without having the polk cable? Thanks..
