DUDE!!!!! I have the same problem!!!!!! I just purchased those from a local AV retailer and here's how I have mine connected. Marantz receiver LFE out to audioquest Y splitter, two Sub x cables into 8060 towers, speaker wire connected accordingly, and I cannot get the damn blinking lights to stop!!!!! (settings Large Fronts, SW yes), I even tried Front Large & No sub and still constant damn blinking. I contacted definitive and they say it's a blown amp inside the speaker and was like What!!?. For a moment, I had a constant red light, powered on my Marantz and it went Green??! WTF? I have never seen a green light on definitive products. It was a very low bass response at sub level turned all the way up on tower and after 5 min, started making a weird popping rumbling noise!! I'm not taking a chance and back to the retailer they go for a new set or different speakers.
