my pioneer receiver + four 12" 3-way MTX + 100watt 10" sub + soon to be center speaker will pwn all of those systems hands down.
they really dont make sound systems like they used to. i dont even need the sub, i only have it on for movies when i want that extremely loud rumbling like they have in theatres once in a while. it gets annoying though, subwoofers really arent necessary when you have a 12" woofer in each corner of the room.
