I was recently in a local speaker shop looking for a sub and I found this guy.
The Donner Haus DH-10. The sub sounded great in store (they always do ) but I would like some opinions of people who have purchased this particular sub or at least the brand name. As far as I know they are from the UK, and this sub is supposed to retail at $799.99 but the sale sticker is $299.99. I am really temptd to jump on it now (I have no sub currently ).

Also, can anyone quickly explain how to hook up a sub only using speaker wire? I have an older receiver that only supports 4 channels and has no sub pre-out, I have been told this is possible but I am still at a loss as to how, also can I still have 4 speakers if I hook up the sub? Thanks all!!
