Hi,

I've posted about the following issue on AVS forum and I've already contacted LSound about it, but since there seem to be a lot of fellow SVS users here I thought I'd post this message here as well, to see if anyone has experienced something similar.


Since last friday I own a PC Ultra 13. I live in the Netherlands, Europe and since these cylinder subwoofers have just recently been officially been introduced in Europe there probably haven't been sold that many in this region yet. However, I'm already having a problem with mine: after it has been turned on for about 30/45 minutes it stops producing any sound. It doesn't matter if I'm actually feeding any signal to it during that period or that it is just sitting idle: after those 30/45 minutes it doesn't do anything anymore. The green light is still lit though and if I hold my ears close to the subwoofer and listen very carefully I can still hear some faint sound that sounds like fan noise, which I assumed was coming from a cooling fan in the amplifier (but from what I've heard this amp doesn't have any active cooling, so I'm not sure what noise I'm exactly hearing here).

Whenever this happens I have to turn off the subwoofer using the hard power switch, which by the way results in a rather loud 'popping' sound. Then, after waiting a while (last time I waited about 10 minutes) I can turn it on again and then it does work again (but again, only for a maximum of 45 minutes). By the way: turning the subwoofer on also gives a rather loud 'pop' noise (measured at about 95 db), but not as loud as the one when it was turned off (which sounds more like a kind of rattling sound).

Now I haven't been playing anything loud yet, I have only been playing at very moderate volume levels, so I doubt it has anything to do with overloading the amp or something. I also have the AUTO/ON switch set to ON, so it can't be that it is automatically going into standby mode. Has anyone else ever experienced something like this? And if so, how was it solved? I'm hoping I don't have to return the complete subwoofer...

Sorry you are having problems with your PCU. Sounds like a bad amp; L-Sound will arrange to replace it and provide you with detailed replacement instructions.
