So I have been thinking about this for a while. I currently have a Bose Acoustimass 10 system. I was thinking of adding an SVS 20-39 PC+ to my setup. I was also considering replacing the entire bose setup with a new set of Axioms consisting of the M22Ti for the mains, the VP100 center, and the QS4 for the surrounds. Of course if I replace the Bose system then I'll be able to auction it off. Its just a question if the Bose should be kept longer or not. Any input would be great. Thanks.
