I would most likely open it up and look at it with my own eyes.
The phillips sonowave main speakers have three built in identical sized woofers. They are wired with six wires, so the philips machine that controls the speakers probably simply powers the three on some sort of delay to give the desired surround effect. I want to bypass this and run the triple speaker as a single speaker with my receiver. How can I test the wires to see which wire is positive and negative for each individual built in woofer? The colors are black, red, yellow, brown, orange, green so that isn't helping me. They say 8 ohms so I would run the three in a series to keep them at 8 ohms. But how can I find which wire is which? Phillips support is worthless and won't give me any info at all. I want to try this is because these speakers have a great aesthetic appeal due to their narrow size, and judging by the heavy weight and original price they appear to be made with excellent quality. Thanks much if anyone has some technical knowledge on this and knows an easy way to test them! -Shane
