if you have them on the wall, which I think is a viable placement option, you might at least want to tilt them downwards towards the listening position. Your comments echo why I went with the Ref 3.5 as opposed to the simple Stradas. I was concerned that the two 4" woofers wouldn't provide enough mid-bass punch. with the ref 3.5 the 10" woofer does not have a crossover but naturally rolls off at around 500 hz. I also have them crossed over at 80 hz to a pair of subs.
what really characterizes the sound to me is the way drums sound. Lots of impact and a very unique and natural sound. Music is very percussion driven with the Ref 3.5. Plenty of detail, but perhaps not quite as in your face as from the Volent paragon VL-2 that I used to have with it's twin ribbon, but the detail is still there and very musical. Left and right motion is also very good and I get a huge soundstage in the room. I am driving them with an AVA U70 tube amp so i only have 35 watts a channel on tap, but plenty of dynamics.
Best of luck, I think these are fine speakers and you just need to find the right spots for them.
