Well, (to treat this seriously, rather than the joke it was) where's your transmitter? And are there vibration-sensitive components inside of either the transmitter or receiver? Several times a month, cars idle outside my apartment with bass loud enough to severely shake my windows, and somewhat shake my walls and floor. I imagine a receiver that's physically attached (or merely very near) to a subwoofer that loud would have trouble maintaining a steady optical link.
