Yeah thats always fun, I remember when my current sub first arrived and at the time I was living in a townhouse and I had the HT setup upstairs. Lots of fun, dragging the 150 lbs up a flight of stairs. At least it slides pretty well on carpet .
I'm actually getting rid of it soon if anyone wants it. Going to replace it with one of the new SVS PC-Ultra's. Much smaller footprint and weighs about 60 lbs less.
