EarthQuake HoLeeS-12 Introduction

Introduction to HoLeeS-12
Congratulations and thank you for trusting in us
and acquiring thenew HoLeeS Competition subwoofer,
another incredible subwoofer from the mind and soul of Mr.
Joseph Sahyoun (President of Earthquake Sound). "I really
worked very hard on this driver for several years now, and
wanted to perfect every aspect of the driver before it was
released."
"This sub is constructed from the finest parts on the
planet; and I mean it." When it comes to the surround, much
attention to detail is required to accommodate the huge
amount of excursion and pressure that will be applied. The
surround uses Polyether Draw, the strongest and longest
lasting material available. When the driver is in a long
excursion situation, you will not start to see any
deformations or dimples unless the speaker is being
pushed to it's absolute max peak. Unlike many
subwoofers, HoLeeS's surround will not deteriorate after a
few years of hard-core pounding; the surround has a
working life span of 10 years plus. This wide surround will
easily outlast any other and its many qualities make it the
widest, longest lasting and most reliable surround, period.
The driver is constructed with a unique triangular
bridge type design. The voice coil pushes on the flat piston,
not the cone. The cone is used for assembly purposes only.
HoLeeS's cone is connected to the flat diaphragm and its
lattice structure in the middle, creating the triangular
system that removes cone distortion caused by wobbles,
found in typical speaker designs. Earthquake's HoLeeS

1000W 1500W
Blue (Minimum):
If you are powering your sub in this
range, it will operate comfortably with
zero strain or fatigue. Power ranges
this low will not damage your
speaker, but it wont capture the
Subzero full capabilities.
Maximum Don't
3000W
Yellow (Optimized):
This zone represents the best
compromise between long-term
reliability, high-output and low-
distortion. If you are operating your
subwoofer in this range you are
taking advantage of the best low
distortion and sound quality that the
Subzero is capable of delivering
between the recommended power.
uses a voice coil that is built with an aluminum bobbin and
military-grade flat surface wire. The voice coil is over 3" in
winding height and diameter which makes it one of the
most respected drivers for producing high excursion, not
only does it move a lot when you press on it, it has the
electrical force necessary to move it the distance of the
actual voice coil. During movement, this driver pulls less
current from your amp than any other speaker on the
market. Since it is designed and optimized to have a higher
impedance during working periods (reactive impedance), it
never goes into compression and to do so it would have to
move double what is out there. The "PSP" terminal (patent
pending) allows the users to have their speaker in 2-ohm,
dual 4-ohm or 8-ohm. As you can see this terminal and the
rest of the speaker are the first of their kind and we are
extremely proud to be the brains behind them.
Earthquake Sound is a reputable manufacturer of
high-end home and mobile audio products for nearly 20
years. You will notice that the engineers and other parties
involved with the production of these fine subs covered a lot
of ground making sure that every user is satisfied and
educated as much as possible. If there is anything that you
do not understand or need help with or if you have
comments please feel free to contact us at (800) 576-7944

In this zone low-distortion and sound
quality become compromised.
small amount of SPL can be gained
in this zone, but only a couple of dB.
Remember that the more you travel
out of the recommended power
range the greater the chances of
failure and warranty rejection. Be
wise and use extreme caution and
care with your speakers.

Black (DON'T):
In this zone the chances of failure are
A almost inevitable. When exposed to
excessive heat and/ or mechanical
stress the driver will loose sound
quality, SPL and could seriously
damage the driver or you vehicle.
