Subwoofer Placement
The goal of proper subwoofer placement is to set up your system so that your
subwoofer acts as a natural extension of your full-range monitors without
boosting the overall bass response of your room or exaggerating any one
frequency or frequency range. Because low frequencies are not directional—
that is, humans cannot perceive the direction from which low frequencies
are coming—you aren’t limited to placing it near your full-range monitors.
However, placing your Sub 8BT in the same side of the room as your full-
range monitors will typically provide the best listening experience.
A quick way to find the best location for your subwoofer is to temporarily
place it on the ground where you would normally be listening to your system,
then play some music that contains a lot of bass. Walk around the half of the
room where you have placed your full-range monitors until you find the spot
where the bass sounds its best. In general, you will want to avoid placing
your subwoofer too near to reflective surfaces, like a wall or in a corner as this
will exaggerate the bass energy and make your Sub 8BT sound “boomy.”
Once you find the place in the room where the bass sounds the smoothest,
place your Sub 8BT in that spot, return to the listening position, and listen to it
again. You may need to adjust the location; just keep making small adjustments
(a foot or so at a time) until the bass response sounds as even as possible.

Level Calibration
Matching the levels of the monitors in your system with your subwoofer
is an easy extra step that will help you to achieve a consistent listening
environment. This will ensure that your subwoofer won’t be too loud with
some types of music and not nearly loud enough with others. You will need an
SPL meter and some pink noise to do this; luckily, there are many inexpensive
and free SPL meter apps for just about every type of smartphone, as well
as a variety of free pink noise samples online that will do the job nicely.
