C 80 SUB
If you go to www.Jamo.com or look at the CD-rom which came with the product,
you can fi nd a couple of useful subwoofer test signals. These will help you to set
up your subwoofer so it delivers the maximum performance. Burn the test signals
onto a CD and put them in your CD/DVD player.
Placement rules for subwoofers
When placing a subwoofer in a room, you have more freedom than you would
with an ordinary speaker because a sub generates less-directional low frequencies,
which make it harder for the human ear to determine the direction they are com-
ing from. We do still recommend, however, that you place the C 80 SUB mid-way
between the two front speakers if possible. This is because:
A). The C 80 SUB will be easier to align, both level- and phase-wise, with the speak-
ers.
B). Even though low frequencies are less-directional, higher frequencies can make
the subwoofer easier to pinpoint sonically.
If it isn’t possible to place the C 80 SUB between the two front speakers, the ad-
vanced electronics provided in the subwoofer still makes an easy and seamless in-
tegration possible.
Three different placement positions
- sound refl ections and amplifi cation
There are basically three different ways to place a subwoofer, either of which will
affect the overall sound level.
A). Placing it away from any wall will give the lowest sound level, but typically the
most linear frequency response.
B). Placing it next to a wall will increase the low frequency level.
C). If it is positioned up against two walls, i.e. in a corner, the subwoofer will - be-
cause of wall refl ections - accentuate the low frequencies even more.
