0000062458 00000 n This is why the location of the subwoofer relative to the back wall has a significant impact on the overall low frequency reproduction quality and musicality. All of us married guys have this to some degree. As a result, their radiation patterns display an ideal cardioid (heart) shape, with 15 dB higher level at the front than at the rear.

But due to room layout and wife acceptance factor, there's only one place I can put the sub - to the left of the TV, backed up against a wall. Sony PlayStation 3 Advanced Control Roundup, Universal Remote Control Inc. Digital R50. This will ensure that the low frequency output is not compromised, because there is no distance behind the subwoofer.
This said, there still is the need for a minimum distance between the cardioid subwoofer and the back wall. Due to the fact that every room (geometry, furniture, etc.) Noch keinen Account?
Hence, we can conclude that if a subwoofer is placed 1.0 m away from a hard, solid wall behind it, its forward-radiating frequency response will display a significant notch in at 83 Hz.

In that case, using our numerical findings above our subwoofers can be placed either; In doing so, you will ensure that the subwoofers low frequency reproduction remains unaltered over the entire band pass. In order to avoid these strong low frequency cancellations, we could first choose to place the subwoofer as close as possible to the back wall. I was afraid it would rattle; luckily it didnt (there was no way to find out before the whole cabinet was built). Rob here`s a slightly different way to do it. If this same subwoofer is placed anywhere between the 0.78 m and 2.15 m range, the subwoofers output will lack definition, punch and tight dynamics with, possibly, some bass notes missing entirely. 0000003432 00000 n When you find the spot where the bass sounds the cleanest thats whre your sub should go.

In all KS Series subwoofers, the ultra-compact, single 12-inch KS112 has the widest frequency response (-6 dB) that spans from 41 to 108 Hz.
To enhance the overall listening and performance experience, their placement in a room, on stage or below it is, in fact, critical. I`ve used this method with great results.
