Measurements inside a room are very sensitive to sub placement, listening position and the dimensions of the room. Placement against a solid wall or in a corner often gives the best low frequency reproduction. The measurements below show the response in a corner *, in down-firing position, with a 24 dB/ octave Linkwitz-Riley low pass at 60 Hz or 80 Hz without a high pass. Based on hearing alone the response drops off quickly below 17 Hz.

* One thick stone wall, one thin stone wall and a wooden floor
