| | The placement of a subwoofer |
 | | Regardless of the order of importance between the speaker and the room, it is obvious that as well as the choice of a loudspeaker should be made with the greatest care, the same is valid for the attention to the acoustics of the room and the proper placement of the loudspeakers therein. |
 | | By using two subwoofers instead of one, and placing them in opposite corners on the same distance from the listener, (it is best done in each corner behind the main speakers) there will be an obvious reduction of the room resonances, while the directly radiated sound pressure will increase. |
 | | This is because a subwoofer as a sound generator does not have infinitely high mechanical impedance, it will therefore play the room resonances a little weaker when it is placed in the corner itself, than when it is placed in the sofa and we listen in the corner. |
