I guess, I could add to this. I do not use mine in a HT setup but i wanted to just list how I run mine.
I have them running from a cayin a50t in trilinear @ 16 watts . The volume knob is only at 10'o clock and I do get bass from them in my vinyl setup.
So they can sound very good with low wattage. I sit about 6-7 feet from them.
