My receiver at max volume could still probably damage the speakers since it will not be clean power, that being said I don't listen to them at max volume. With my Polk Audio's (90db sensitivity), I watch movies at -15db. I'm curious to see what I'll need to listen to the SVS's at to reach the same volume, surely it's not as simple as -11db, since there is a 4db difference in the sensitivity. I guess we'll find out.
I went ahead and ordered the Prime center, bookshelves and satellites. With the Ultra center being twice as much I want to give the Prime center a try for a while. Worst case scenario, I'll upgrade to the Ultra within the first year if I feel that it is necessary.
I have read others state they heard a huge difference when switching from the speakers that I have to the SVS Prime series, I anticipate a rather large upgrade.
