Today I bought a SoundStage Cinema Stage home threatre package for $900 (I live in Canada...darn high prices here) not including tax. My brother wants a subwoofer for his place and knowing that I have two subs already, I'm thinking of selling the sub in the package to him. This is where to problem comes. I have no idea how much the sub would cost. Here is a link to the SoundStage site to view the package. http://www.soundstage-audio.com/products/cinema_stage.html How much do you think the sub would cost?
