Most of the big box stores sell "home" brand speakers like Precision Acoustics (Best Buy) or Quest (Future Shop), that are all "designed" in Canada and assembled in China and imported by companies like Jam. They are very similar in design and I wouldn't be surprised if they all use the same components.
The "better" siblings of Quest are Sinclair that are now sold in The Source.
As far as sound is concerned, they do the job, but you obviously can get much better (at alot more cost, of course).
Sound Stage speakers look alot like the Precision Acoustic speakers from BB, but seem to be quite a bit more pricier at $400 a pair, especially since BB has them on sale quite a bit. I think that for that much money, you can get better quality (and get a brand name for bragging rights on this and other audio forums
)
But hey, if they sound good to you and you are happy with the sound, who am I to say otherwise.

On closer examination, they may be better than PA or Quest, maybe more along the lines of Sinclair quality (quality that may very well be debatable?)
