Picked up a set of these after seeing the post in the bargain forum but try as I might, I can't get these speakers to work when connected through the supplied sub. They work fine connected directly to my amp [Pioneer VSX-D912] but they sound tinny [obviously 'cos no bass]. I'm using them as rears so the sub may not be essential anyway. I've checked and rechecked the cables but my amp keeps giving me an overload message and then shutting itself down. I have them connected to the surrounds terminals on the amp. I've heard of people having problems connecting rear speakers to the back surround terminals so I haven't tried that yet.
