Safe & Proper Handling Of Your SuperNova  
The SuperNova MKV subwoofer system weighs over 80 Lbs. It is considerably heavy for  
an average person to carry or maneuver. To prevent injuries and eliminate any possible  
damage to your SuperNova MKV, we encourage you to employ the help of a friend when  
unpacking the unit; further we suggest the following:  
#1. Always wear a back support belt when carrying / lifting the SuperNova MKV.  
#2. If possible, get someone to help you move the SuperNova MKV.  
#3. Do not apply pressure or push against the face of the speaker; this will cause  
irreparable damage to the cone and suspension.  
#4. When carrying the SuperNova MKV, make sure that the speaker is on the other  
side, away from your chest (eliminating the chance of pushing against the face of the  
speaker).  
#5. Do not drop the SuperNova MKV or subject it to sudden shocks. This will damage  
the external finish and weaken the enclosure, creating air leaks.  
#6. Avoid exposing the SuperNova MKV to moisture. Water will damage the wood  
structure as well as the amplifier and speakers.  
#7. Cleaning the SuperNova MKV is best done using soft cloth; if needed, use mild  
detergent with water. Like with any other electrical unit, always unplug the MKV before  
cleaning it.  
Unpacking Your SuperNova  
The SuperNova MKV is double boxed for product safety. We highly suggest having a  
padded surface and at least two (2) people to safely unpack the SuperNova MKV.  
Step 1  
On a padded  
surface, carefully  
place the box on its  
side to remove the  
bottom packing tape  
and staples.  
Step 2  
Step 3  
Gently reposition the  
box upright.  
Without tilting the  
box too much, tug  
the bottom flaps  
outward and keep  
the protective foam  
in place.  
Step 4  
Slide the box off,  
minding the protective  
foam on the top,  
bottom, and sides of  
the subwoofer.

What Makes A SuperNova?  
Premium Earthquake Subwoofers  
Every component of an Earthquake driver is designed for  
accurate reproduction of bass and sub-bass frequencies. With a  
massive moving structure, these subwoofers operate with  
extremely low distortion and impressive transient response. Their  
performance is attributed to a non-conventional motor structure  
design that integrates components such as:  
Telling The Difference Between The Passive  
and Active Drivers  
10” models: The 10” SuperNova MKV has a  
deep-cone active driver with the Earthquake logo  
on the front of it. Its SLAPS passive radiator is  
flat and has no logo.  
* Double stacked, high-gauss magnets, with a total height of  
1.5 inches  
* Over 7 inch (D), epoxy coated super spider. Chill-plated for  
long lasting linear performance  
* 3” diameter, high temperature voice coil, with 1.85” copper  
winding (height)  
12” and 15” models: Both of these models use  
flat active drivers and passive radiators which  
both look almost identical. But they are not; the  
one with the bolt head in the center is the SLAPS  
passive radiator.  
* 1.5” thick, single layer, thermally pressed poly-ether foam  
surround  
The SuperNova subwoofer structure allows high excursions (19  
to 21mm) without physical deformation or running out of Reactive  
Electromagnetic Coupling.  
SLAPS  
Besides its many advanced features, the SuperNova MKV is  
armed with the Symmetrically Loaded Audio Passive System -  
SLAPS (patented by Earthquake Sound Corporation). The  
SLAPS is capable of moving more than 4” peak to peak at 15Hz.  
More air movement translates to higher SPL; the new passive  
system adds an excess of 5dB at 15Hz, that is more than twice as  
loud at that frequency.  
How is that possible? Current passive woofer technology relies  
upon non linear, limited movement suspension. In contrast, the  
SLAPS employs dual (identical) suspensions, allowing the  
passive driver to move the same amount of air in either direction.  
Further, the components used to build the suspension allow for  
long excursions with no physical deformation or limitations.  
SLAPS used in SuperNova MKV are tuned by  
adding mass to the structure of the passive  
radiator. Steel cylinders are used to tune the  
SLAPS to the desired frequency.  
THX Standards... One Octave Lower!  
The SuperNova MKV performance exceeds THX  
requirements of 105 dB at 30 Hz by far... In flat mode,  
it achieves 123 dB at 30 Hz and reaches upwards of  
128 dB when the bass boost from an audio processor  
(source) is used. More impressive is its capability to  
dish out 108 dB at 15 Hz and near 100 dB at 10 Hz -  
as shown in the graphs below. Keep in mind that  
typical subwoofer systems fail to reproduce frequen-  
cies below the 20 Hz mark.  
Brace yourself and everything else in the room... This  
SuperNova will extend the already flat, accurate, and  
on-time low frequency response to deeper levels  
where no other subwoofers have gone before. It can  
put out enough bass energy to fill even large rooms  
with sonic rumbling.  
The SuperNova MKV delivers an impressive amount  
of features aimed at fulfilling the promise of ground-  
shaking bass, as suggested by its name.

Corner Loading = + 9 Decibels Of Free Power  
Fact: Subwoofers reproduce frequencies with wavelengths  
that are long in relation to the dimensions of most living rooms.  
Standing waves will boost or cancel various frequencies due  
to the interaction with the room boundaries. Moving a  
subwoofer in a room will change what you hear in the listening  
position a lot.  
For maximum bass reinforcement, the SuperNova MKV  
system should be placed in the corner of your living room with  
the subwoofers facing the wall. This creates acoustical  
coupling with the walls, which in turn leads to a 9 decibels of  
boost in the overall response of the Supernova. Keep a 3"  
clearance between the subwoofer and the walls.  
Fine tuning the SuperNova MKV requires adjustments to the  
crossover point, volume control and the phase switch. These  
controls are located on the side of the enclosure. For ease of  
tuning, we recommend that you turn the SuperNova MKV  
around to expose the controls, and place it in position (corner).  
Set your stereo system to a moderate listening level and adjust  
the SuperNova MKV accordingly. The SuperNova MKV is  
equipped with a 24 dB/Oct. low pass filter designed to  
eliminate vocals from entering the system. When tweaking,  
gradually reduce the crossover point setting to eliminate  
vocals fromseeping into the amplifier.  
Corner Loading will give you an added 6 to 9 decibels of  
sound pressure; also it reduces the level of vocals - if  
present - emitted from the subwoofer. We recommend  
that the active subwoofer face the listener, while the  
passive faces the wall (corner). Keep a clearance of 5” to  
7” between the SLAPS and the wall - remember that the  
SLAPS can travel up to 4”.  
Positioning Options  
Consider that room permissibility plays a big role in  
positioning. One thing is certain, achieving a  
perfect subwoofer setup in your living room will  
require time and experimentation.  
When used for special effects reinforcement  
(10Hz to 40Hz range), the SuperNova MKV fares  
well in corner loading position; as corner loading  
naturally boosts the subharmonic frequencies by  
9dB.  
Corner Loading is recommended for  
movies and sound trackseffects.

Used with music (10Hz to 100Hz), it is recom-  
mended that the SuperNova MKV is placed in a  
corner, yet it can be placed in a centered position.  
By using two MKV subwoofer systems (one in each

without disturbing the balance of front stereo

Surround System Placement  
Surround speakers are there to envelop three dimensional  
sound that places you in the middle of the action. Ideally, your  
primary pair of surround speakers should be placed to the left  
and right of your listening position — either in line with it, or just  
behind it. They should form a 90°-110° angle with respect to  
your television. In a 6.1-channel or 7.1-channel system with  
more than two surround speakers, or if side placement is not  
available for your surrounds in a standard 5.1-channel setup,  
consider placement behind your listening position, facing the  
front of the room. Surround speakers should be placed high  
enough so that the drivers do not fire directly at your ears when  
you’re sitting down. As a rule of thumb, place them at ear level  
while you are in standing position. Most people tend to over  
amplify the rear speakers. This is not recommended as it can  
overpower the front speakers. Most of the time, the rear  
speakers are relatively quiet. They simply come on when there  
are special effects.

Since every room has different acoustics, you might need to  
experiment with the speakers aiming. You may get good  
results by pointing them at the ceiling or toward the rear  
corners of the room. If no side or rear walls are available for  
mounting your speakers, try placing a pair of traditional  
bookshelf speakers on speaker stands, slightly behind and to  
the sides of your listening position. Avoid aiming them directly  
at your listening position. You may also try any of our Sweet  
spot, IQSeries and Imãge in-ceiling speakers.

Connecting Your SuperNova  
Low Level -RCA- Audio Input Connection:  
This is the best way to drive an audio signal into the  
SuperNova MKV. Today, all signal processors (5.1/6.1 and  
more advanced ones) come equipped with built-in pre-  
amplifier outputs (RCA) that include a subwoofer output.  
From  
Receiver/  
Pre Amp  
Generally, the SUB/OUT is in mono format. Connect  
the SUB/OUTfrom the processor to the SuperNova MKV using  
a “Y” connector to feed both RCA inputs of the SuperNova  
MKV. However, you can connect the SuperNova MKV using  
just one RCAinput as well.  
We strongly recommend that you use the best  
available RCA connectors and cables. High quality cables are  
normally triple shielded and the connectors are gold plated  
with forceful grasping.  
To MKV  
Low Level

High level audio input connection:  
This is the least desired way to drive an audio signal  
into the SuperNova MKV subwoofer. Older stereo systems are  
not equipped with pre-amplifier audio outputs, normally they  
come with stereo speaker outputs (left & right).  
Using “banana” plugs, connect the speaker outputs to  
the corresponding MKV high level inputs (marked “FROM  
RECEIVER”).

Using The Remote Eye  
Wireless remote with eye:  
Earthquake’s advanced remote eye system and remote control  
are easy to use and setup. This three piece system is for  
controlling your systems bass volume. Allowing the bass to be  
adjusted by isolation is great for demonstrations and for stealth  
subwoofer installations.  
Installing the remote eye is very easy; simply plug the provided  
1/8” jack to the REMOTE connection on the SuperNova MKV’s  
amplifier plate. Once you have found a good location that suits  
your needs best, mount the eye and run the cable from the amp  
tothe eye.  
AC power connection:  
The SuperNova MKV is available in two models: 110V  
and 220V/24. The power socket if fused to protect the amplifier  
from surges. Do not overfuse, replace the fuse with identical  
value.  
Fuse holder:  
The fuse holder is located directly under the power  
socket. Itcontains two extra fuses, 10 amperes each.  
To access the fuse holder, make sure your SuperNova  
MKV is turned off and unplugged from both the wall outlet and  
the amplifier’s power socket. Place a flat head screw driver in  
the groove on the top of the fuse holder and simply pry off the  
fuse holder.

Setting Up Your SuperNova  
The SuperNova MKV is a true subwoofer, it must never be  
operated above the subharmonic/harmonic frequency  
range. The frequency response is limited by the built-in  
crossover (with an upper end of 150 Hz); however, in most  
applications, the crossover should not be set above 80Hz.  
It is equipped with a fourth-order Linkwitz-Riley filter which  
will block vocals frominterfering with its performance.  
SuperNova MKV, volume level under the 10 o’clock  
position - you might experience some clipping (overwhelm-  
ing the SuperNova MKV input capability). We suggest that  
you feed an audio signal into the Supernova through  
(using) ONE (1) RCA input instead of using both the RCA  
inputs of the Supernova.  
7- With the crossover open to 150Hz, you will hear vocals  
coming out of the subwoofer. Gradually reduce the  
crossover point until vocals are eliminated (typical crossing  
point of 80Hz).  
When setting up the SuperNova MKV as a part of a home  
audio system, users must understand that the subwoofer  
requires different settings: one for music, and one for  
playing movie tracks. In order to set up the SuperNova  
MKV for music, users must recognize the frequency  
response of their existing speakers (tower & surround  
sound) and the limitations of these speakers, i.e. the  
diameter (size) of the speakers and the SPL.  
To control the volume level of the SuperNova MKV, use the  
surround sound processor output controls; do not use the  
main volume knob on the SuperNova MKV (keep it  
between 10 & 2 o'clock position). Once you set up the  
proper mix of low frequencies and subharmonic response,  
that does not encroach on the rest of the speakers. Now  
you are ready to set up the SuperNova MKV for home  
theater use.  
Formusic setting:  
1- Position the MKV in the corner of the living room.  
2-Turn the unit around toexpose the controls .  
3- Turn on your audio system, and switch your surround  
sound processor to “MUSIC” mode, and equalize the rest  
of your audio system.  
4- Connect the SuperNova MKV to the processor, using  
high quality (triple shielded) RCAcables.  
5- Set the crossover to 150Hz - maximum position,  
volume at minimum (0).  
6- Gradually raise the main volume knob (between the 10  
o’clock to 2 o’clock) position, optimizing for the subwoofer  
performance. That is when the Optical Compression  
Circuitry works best, allowing the amp maximum output  
with minimal distortion.  
For movie viewing:  
The SuperNova MKV can be set up to your liking. There is  
no rule of thumb to how much bass is required. Often,  
users like to feel the overwhelming bass, it brings the  
actions and events closer to real life. When viewing  
movies, a 10dB gain above music setting is often pleasant,  
it brings movie viewing close tolife.  
If you desire to have a crossover setting for music, different  
than the setting for movie viewing. We suggest to cross the  
SuperNova MKV at higher frequency setting, and use the  
processor tocontrol the desired lower crossing point.  
VERY IMPORTANT: some of the newer audio processors  
come equipped with high level voltage on the RCA  
subwoofer outputs. In such case - even with the  
Crossover knob in 1 O'clock position - 85Hz @ -3dB.

Seamless Transition Between Subwoofer and Speakers  
The fine tuning process includes  
creating a smooth transition of music  
between the SuperNova MKV and the  
next speaker in line : usually a woofer or  
a large midrange. As shown in the  
graph across, a smooth transition  
between lower and upper bass is  
directly relative to the crossover setting  
and the capability of the next speaker in  
line toreproduce low frequencies.
