FWIW, I use three B&W LCR 6 S2's for my front soundstage with B&W in ceiling surrounds. I have a Rotel receiver w/70 wpc and it powers the B&Ws just fine. The B&Ws work well for music and home theater and I have a big room. I picked up two Velodyne 10" subs (SPL10? I forget) for my low frequencies. Been using the speakers/subs for 11 years and they work great. The rotel is my second receiver after my Marantz died in year 6 (one year out of warranty) and it was a motherboard failure (no longer available) so I picked up the Rotel.
Hope that helps.
