Rumbling the walls is more about the volume you're playing at and the frequencies of the music/movies, not the sub. If you really just want to not reproduce low frequencies, buy an in-line high-pass filter for the sub to keep the low frequencies from going to the sub.
I think either of those choices would be good ones. I've been happy using a VTF-2 with my Ascends since I bought them and the Onix UWF/ULW-10s are also very nice subs (I've heard them, but not in my system).
