The Sound That Will MOVE You...

www.earthquakesound.com

Getting tired of the “just me” type of
subwoofer tube, Joseph Sahyoun (VP of
Earthquake Sound Corporation)
integrated the newly patented
Symmetrically Loaded Passive System ­SLAPS into the smallest most compact
tube; thus creating the “KOMPRESSOR”.
The latest and most advanced bass
cylinder to ever exist.

The SLAPS allows to tune the subwoofer
tube in the car to ridiculous low
frequencies, and at the same time get
massive amount of SPL in the sub­harmonic range. The KOMPRESSOR ­compression - is technologically the most
advanced tube available in the market
today. The small package address looks
and performance: the drivers move clearly
beyond the norms of any other drivers -
over 3”. The KOMPRESSOR is
guaranteed to shake loose the trunk of
your car and its contents.

Here at Earthquake, we believe that good
bass does not have to be expensive, it
does not have to eat up your trunk space
either. Earthquake engineers wrote the
book on deep bass extension. First, they
molded tube enclosures from high density
material; next they developed new drivers
optimized specifically for use in these
tubes... Hence, the “K” subwoofer tube:
the easiest and the most economical way
to add deep, clean, all around bass to your
existing car audio system.

The tube construction is rugged, with
durable moldings designed to blend with
any car interior. All hardware needed to
securely mount the tube is included in the
package. The “K” subwoofer tubes are
passive tuned with the “SLAPS” for
optimum bass response and long lasting
performance. The drivers feature 4-wound
flat wire voice coils (2" diamete
r), for deeper low frequency re sp on
se and smooth high frequency roll off;
thus eliminating the need for
external
crossover.
The Long
Throw piston assembly
provides excellent sub­harmonic extension.

CAUTION: the

KOMPRESSOR

tube subwoofer is

capable of generating

high sound pressure

levels. You should exercise

caution when operating

these speakers. Long term

exposures to high levels of

sound pressure will cause

permanent damage to your

hearing. Sound pressure levels

exceeding 85dB can be dangerous

with constant exposure, set your audio

system to a comfortable loudness level.

Earthquake Sound Corporation does not

Before you begin:

1) Locate an area in the rear of the vehicle where you would
like to install your tube subwoofer.

2) Orient the subwoofer so that the active driver- front of
the tube- fires into a corner, about 2 to 4 inches away.

3) Inspect the mounting area to ensure that the mounting
screws will not damage the gas tank, electrical wiring, fuel
lines, spare tire, or any other parts of the vehicle.

4) Ensure that the chosen surface is solid enough to
withstand the stress of subwoofer mounting.

In a hatchback: the tube should lay parallel to the rear of
the vehicle, firing into the corners.
In a sedan: the tube should be secured against the sides of
the trunk, firing toward the rear of the vehicle.
In a trunk: the tube should be mounted behind seat, firing
outward.

RULE OF THUMB: Position the tube so the active
driver is facing a hard reflective surface (3-5”away).
This adds a 3dB gain to the total system response.

In a hatchback: the tube should lay parallel to the

rear of the vehicle, firing into the corners.

Mounting instructions:

1) Place the tube subwoofer in the desired mounting
location and mark the correct place on your vehicle to drill
the required mounting holes.

2) Mount the tube subwoofer by screwing or bolting to the
vehicle through both holes in each leg. Be sure that your
tube subwoofer is securely fastened to your vehicle!

Note: Due to the shifting and jarring that will occur in a
vehicle, the mounting legs should be checked periodically
to ensure that they are fastened securely in place.

Wiring instructions:

Locate the terminal cup on the rear of the tube subwoofer.
Insert the positive speaker output lead from your amplifier
into the gold plated red terminal on your subwoofer tube.
Repeat the process with the negative amplifierlead and
black terminal

Wiring multiple tubes:

Care should be taken to wire all speakers in proper
relativephase. However, if your bass response does not
increaseafter wiring an additional tube, you must reverse
its' polarity.To accomplish this, turn off your system, then
reverse the leads on the second tube subwoofer. If the
bass response improves, your phasing is correct.

In a sedan: the tube should be secured against the
sides of the trunk, firing toward the rear of the
vehicle.
