Pardon me! I'm not familiar with the speakers and home theaters. I recently bought Klipsch R51-PM bookshelf speakers. Its working amazing. Can I connect it to the Klipsch R-12SW Reference Powered Subwoofer to it (which I bought from costco recently) ? OR Shall i go ahead with Klipsch Reference Theater Pack 5.1 Channel Surround Sound System instead of the bookshelf + subwoofer combo? My usage is, mostly I'l stream the songs via bluetooth from my phone and digital output the TV?
