Aperion Audio 8D - Installing Subwoofer Feet

Installing Subwoofer Feet
After unboxing your subwoofer, the next step is install-
ing the feet. Due to the weight of our subwoofers, we
recommend this step be completed by two people. Take
your subwoofer out of the box, but leave the velvet and
plastic bags on the subwoofer. You’ll also notice a bag
of metal spikes and rubber feet included in your packag-
ing. If your subwoofer will be placed on carpet, use the
metal carpet spikes as your footers. For surfaces other
than carpet, such as wood, tile, certain tight weave rugs
or vinyl, use the included metal disks under each of the
spikes, or the rubber feet to prevent damage to the floor
or floor covering.
To install the subwoofer spikes follow these steps:
1. With the velvet bag still covering the sub, gently roll it
onto its top - exposing the 4 metal, round inserts on the
bottom.
2. Gently screw each of the feet/carpet spikes into the
threaded holes on the underside of the subwoofer. DO
NOT force or cross-thread the spike. (See Figure A be-
low.)
Note: If the sub is going to be placed on a surface that
may be damaged by the carpet spikes, place one of
the included metal disks under each spike, or use the
included rubber feet.
3. After all four spikes have been installed, gently roll
the subwoofer upright. If your sub is not sitting evenly
on the floor, use the jam nuts on the spikes to level the
subwoofer. (See Figure B below.)
Placement
The location of your subwoofer will greatly affect how
evenly the bass is distributed throughout the listening
area. A subwoofer that’s placed correctly will give you
even, accurate sound throughout its frequency range.
Here are a few guidelines for getting the most out of
your subwoofer:
1. The best way to place your subwoofer is to use the
rule of 3
rds
or 5
ths
. To execute this, measure the width
of the front or side wall of your theater. Then split that
length into either 3 or 5 equal parts.Your sub can be
placed centered between any two parts (see below).
2. If your room doesn’t allow for 3
rds
or 5
ths
placement,
place your subwoofer near a corner to help eliminate
uneven bass in the room. If you do place it in a corner,
be sure it has at least 3 inches of clearance on all sides.
3. If a corner is impractical, the next best place is
anywhere the room will allow. Your new sub has a wide
range of adjustments your can make to fine tune its
performance.
4. If you use more than one subwoofer, put them in
asymmetric places relative to walls and open areas.
Asymmetric placement is good for bass in that it can
help create a grid of sound in your room. Again, 3
rds
or
5
ths
placement is best, then corners, then wherever it fits.
