Hello all, Yesterday I bought a Pioneer HTiB setup from Costco. The speakers are mediocre but I bought the package for the VSX 711 receiver, which I've read to be excellent. Anyway, I'm trying to figure out what's going on with my subwoofer placement. I was watching parts of Shrek and I could hardly hear the sub, but my wife was upstairs and complaining that it was extremely loud. I went upstairs to find the house vibrating from the sub. I originally placed the sub in a corner to my right, with the port facing me. I'm guessing that the sofa was absorbing the soundwaves which essentially killed any bass I was hearing. I now have it placed just to the left of the TV, with the port facing me. It's better now, but I'm wondering if there's another place for me to place the sub. Would I get more effective sound if I aimed the port at a wall with no obstructions in the way?
