Introduction
Simply put, the THOR is the only in-wall subwoofer that
sufficiently provides bass to your home theater system.
The THOR remains stable and maintains next to zero
resonance because the user can bolt the THOR directly to
the studs from the front of the unit.This locks theTHOR into
the structure of the home. Earthquake engineers also
added four dog ear fasteners for added sheet rock support.
There are two inches peak-to-peak out of a standard 16”
stud gap.
engineers maximized the small amount of given air space.
This style of enclosure also helps deliver a very clean and
deep impact bass. THOR’s back-box is constructed with
extra thick high-temperature PVC and is reinforced from
front to back all the way through the cabinet. Three
methods of reinforcement designs ensure the THOR’s
prolonged strength, durability, and maximum dampening
capability. The first is the front to back bridges that sur-
round the drivers. At these points the cabinet is most
vulnerable to flexing and warping over time. Not theTHOR.
THOR’s bridges are locked using the mounting screws and
can literally be stood on top of by a 200 pound man. Fiber
fill was also used for added resonance protection. And last
but not least, crisscrossed ribs across the bottom of the
enclosure make this in-wall enclosure the strongest and
most durable. This type of internal bracing and attention to
detail is only used in the IW-SUB10 and only at
Earthquake.
Arguably, the IW-SUB10’s best feature is the SWS
subwoofer. The SWS driver has an amazing 10” diameter
but a mounting depth of only 3 3/4”. In addition, the
impressive excursion is almost the same as the mounting
depth. While other in-wall subs struggle to maintain a good
30Hz,THOR will go all the way down to19Hz and counting.

resting position.
Connection Tips
• Keep all power cords away from all signal cables to
prevent humming from induced noise.
13) Unplug this apparatus during lightning storm or
when unused for a long period of time.
• Choose reliable signal cable cords (Earthquake Sound
also specializes in high performance RCA cables and
patches).
14) Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged in a way such as: power-supply cord or
plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate
normally, or has been dropped.
• All speaker wires that are ran through the walls should
be twisted type to reduce potential hum noise pick-up.
• Label both ends of all wires with the corresponding
room location.
• It is best to use a grounded electrical outlet to power
the amplifier. Lack of input ground reference could be
unsafe. Consult with your electrical contractor about
proper grounding.
15) To reduce the risk of fire or electric shock, do not
expose this apparatus to rain or moisture.

Taking Off THOR’s Grille
Connecting Your THOR
STEP#1
Earthquake Sound’s XJ-300FR
amplifier is recommended for the use of one
THOR. The XJ-300FR amplifier is a 300-
watt amplifier and can be used as a mono
block, a 2 channel amplifier, or bridged for a
2.1 channel amplifier.
Your are now ready to prepare the sub for installation.
Carefully remove the logo from the grille to expose the
fastener hex nut.
STEP#2
Using the provided allen wrench, remove the fastener
nut. Make sure you perform these steps before trying to
remove the grille (you will damage the grille otherwise).
STEP#3
Now to remove the grille you simply use your fingers to
push out the prongs from the back side of the unit. Push
out all prongs and the grille will simply fall out.
Earthquake Sound’s XJ-600R amplifier is
recommended for the use of two THORs.
The XJ-600R is a 600-watt, 1 channel, rack
mountable amplifier. In this instance, the
two THORs are parallelly wired.

Installing Your THOR
STEP#1
STEP#3
Note:
These pieces are sheet rock
stabilizers, not brackets.
To begin you will need to locate the empty grille frame.
Use your stud finder to locate the studs (if you’re not
retrofitting). Using the empty frame, trace your cut line
with a pencil. Once you are satisfied with your cut line,
begin your cut using the sheet rock saw.
In the first image furthest to the left you’ll notice the
fastener in it’s neutral position– this is how it is packed.
You will need to turn all fasteners outward so that they
can be clamped to the sheet rock. You will tighten them
from the front once you have fastened the THOR to the
studs.
STEP#2
STEP#4
Note:
Accuracy of stud distance may vary
from frame to frame. It will depend
on the quality of the construction
work.
When the cutout is complete, it should look similar to the
image. Most of the work performed here is installer
common sense, please use it.
Once you have fed all wiring and connected it, slip the
THOR in the wall making sure that the sheet rock
stabilizers are in the correct position.
Begin placing screws inside holes directly into the stud
from the front. Once you have inserted all screws snugly
and securely, tighten the fasteners.

Assembling the Custom Grille
STEP#1
STEP#5
Cut your desired cloth two inches bigger than the frame
on all sides. We have provided cloth that can be used,
but feel free to use different colors or textures.
This procedure is extremely important: Tighten the
dogears by fastening the screws which are located at
the top of the active driver and the bottom of the passive
driver. If you forget to do this the sheet rock will not be
secured and the fasteners will be loose and will rattle.
Make sure that you have two inches of excess cloth
around all sides of the frame.
STEP#2
STEP#6
Cut your desired cloth, two inches bigger than the frame
on all sides. Remember that this is a custom grille so
whatever color or texture of cloth you choose, it will work
for your application.
STEP#3
Congratulations! You have successfully installed the
world’s most effective, efficient and down right loud in-
wall subwoofer ever made. The grille that you use is
totally up to you and can be matched to fit any decor.
(See following pages for custom cloth grille instructions).
Wrap cloth over prongs, make a small incision on cloth
over prong and push prong through cloth. Complete this
process with every prong on the frame.

Assembling the Custom Grille
(continued)
STEP#4
STEP#8
Wrap cloth around frame and put into place with
provided security ring.
This is what the inside of your grille should look like.
Pouring a quick drying glue over the ring and in the
space around where the cloth is will add more support
and provide a hard shell.
STEP#5
STEP#9
Once you have the cloth in place with security ring push
the ring enough to keep in place, though the groove with
cloth underneath.
This is what your finished product should look like on
and off of the sub.
STEP#6
STEP#10
Now that you have pressed the security ring in by hand,
use your rubber mallet to finish securing it completely in
the gap.
When you have completed the project you simply push
the grille into the front of the in-wall subwoofer gently
(use the rubber mallet if needed).
STEP#7
With your security ring in place you can begin cutting
excess cloth from the inner ring. Use extreme caution if
you choose to use a straight razor instead of a box
cutter or scissors.
