You can buy a REL mail order. Doesn't have to be through a local dealer. It's also my recommendation to you. Search the archives. There's a lot of info that couldn't be summed up in a paragraph. leo.
subwoofer suggestions
I am looking at adding a sub to my 2 channel music system. I am using a B&W Nautilus 804 speaker with MF m3 integrated amp and Linn ikemi cd player. People have told me the Linn sizmik, b&w asw 2500 or mirage subs are good. I don't want something too big but I want nice tight bass, not boomy. I here REL is good but there are no dealers in Toronto.
