EarthQuake HoLeeS-15 Introduction

INTRODUCTION TO HoLeeS-15
Congratulations and thank you for trusting in us and acquir-
ing the new HoLeeS Competition subwoofer, another in-
credible 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 re-
leased. 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 ap-
plied. The surround uses Poly-ether Draw, the strongest
and longest lasting material available. When the driver is in
a long excursion situation, you will not start to see any de-
formations or dimples unless the speaker is being pushed
to its absolute max peak. Unlike many subwoofers,
HoLeeS' surround will not deteriorate after a few years of
hardcore pounding; the surround has a working life span of
10 plus years. This wide surround will easily outlast any
other and its many qualities make it the widest, longest last-
ing and most reliable surround, period. The driver is con-
structed 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' cone is con-
nected 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 de-
signs. Earthquake's HoLeeS uses a voice coil that is built
with an aluminum bobbin and military-grade flat surface

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.

This zone represents the best
compromise between long-term
reliability, high-output and low-

wire. The voice coil is over 3" in winding height and diame-
ter which makes it one of the most respected drivers for pro-
ducing 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 amplifier than any other
speaker on the market. Since it is designed and optimized
to have a higher impedance during working periods (reac-
tive impedance), it will never go into compression. The
"PSP" terminal (patent pending) allows the users to have
their speaker in 2O, dual 4O or 8O.
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 over 25 years. You will notice that the engineers and
other parties involved with the production of these fine
subs covered a lot of ground to make sure that every user is
satisfied and educated as much as possible. If there is any-
thing that you do not understand or need help with or if you
have comments, please feel free to contact us at (800)

Once again, we truly appreciate you and your ongoing
support. Thank you.

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.

exposed to excessive heat and/ or
mechanical stress the driver will
