I already have a set of Titans and a Center Channel from Paradigm for my Yamaha receiver which puts out 5X85W power. Looking for a pair of surround speakers to add to that. So far I have narrowed down to dipole Klipsch SS-1 and Paradigm ADP-70 or 170 (and also Diamond DFS). Any recommendations on these or any other model/brand under $300/pair? These will be wall-mounted in an extension of our family room area, so mounting ease and size is also in the consideration. Also, is 50-70W per surround speaker is good enough rating? Appreciate all your suggestions. Thanks.
