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 T8 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 T8 sound “boomy.”
Once you find the place in the room where the bass sounds the smoothest,
place your T8 in that spot, return to the listening position and listen to it again.
You may need to adjust the location; just keep making small adjustment (a
foot or so at a time) until the bass response sounds as even as possible.
