Hello,
This is a quick message to big chris and any one else who owns a PV1 sub and has experienced occasional cutting out issues.
My PV1 has also stopped working after particularly loud or heavy bass scenes. The only remedy seemed to be switching it off then on again, then it would work again. However three days ago i thought i would try and turn the power supply figure 8 cable around. As i am an electrician i have been trying to logically solve the cutting out issue on the sub, without really knowing anything about its internal construction. I thought as there is a coil inside the sub to transform the voltage down, if the polarity of the mains supply feeding it was reversed( live and neutral round the wrong way), then although it would still work, any heavy load like very loud or deep bass might overload the coil and have a negative effect on the circuitry. I have also read on various websites that other kit such as blu-ray players and sky boxes, which also only have live and neutral feeds in a fig 8 connector will work slightly better if you connect them the correct way round. But unlike a subwoofer these devises do not work any where near as hard as a subwoofer so there is less strain on them. So after reversing the figure 8 connector on the PV1 i have been giving it a severe test over the last 3 days, culminating with the blu-ray of "apocalypse now" (i imported it from Amazon.com, which by the way is amazing, one of the best sounding blu-rays), the sound track was extremely demanding on the sub and i had the volume very loud. The PV1 did everything effortlessly and with no problems.
I am very relieved, as this is an expensive sub and i thought it was damaged. I hope this can help anyone else who experiences this issue. I know the PV1's supplied power cable has already been bent into a right angle making it unlikely that most people would reverse the figure 8 connector, however i purchased a new power cable.
