Where is the best place to put a subwoofer in a room?

I know subs are louder in certain places when you walk around a room so im just wondering where i can put it to get the most out of it.

if you are a surround sound enthusiast then the best place for the sub is behind the tv. its worth looking at the construction of your room-do you have floorboards-it may be worth placing a thin peice of foam under the sub to prevent feedback along the floor-this also creates a sweeter bass note. building a sub into coffee tables etc is not unknown but some people do not like cables hanging about the place and you are limited as to where to put the sub (besides the missus might not like it). most subs like the corner of the room about ten inches from each wall the bass will then resonate off each wall along the floor and fill the room. if the sub is of the non-passive type (with its own amp built in) set the volume to about half but this depends on your set-up. hope this helps. .to the poster below-you above everyone else should know that in the audio-visual world everyones requirements differ-no two listening rooms are the same-what may work for one may not work for another-but all rooms have one thing in common-they all have corners!!. hidden under the coffee table or foot stool,in the center of the room Honestly the best spot would be in the farthest upper corner of the room away from the door. So when you walk in you would hear the music in a surround sound state. usually i sit down while watching a movie, i have my subs behind my couch. (this is if ur using it for movies) the best place for a sub is were it sounds the best in your room
