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 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 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’ 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 uses a voice coil that is built
with an aluminum bobbin and military-grade flat surface

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 any­thing that you do not understand or need help with or if you

8-Gauge Speaker Terminals

The HoleeS subwoofers are all about improving the moving parts design of a speaker.
Current speaker designs suffer from several compromising parts that play a major role in
producing a high level of distortions. A huge trend that many designers follow is to increase
the excursion of the driver for a couple of added dB. This may be a good
temporary band-aid, but they still lack compatible parts for the type of excursion that is
being dealt with. If you increase the excursion, you need strong, reliable and better
engineered parts to do the job. If this is not done (which it usually isn’t), then the speaker
will be weak and will have a high level of deformation, non-linearity and distortion. The
HoleeS’ design blocks these bad but common traits from passing on and supports
better over all bass reproduction and sound quality.

1) - Wide Polyether Surround

Earthquake’s Super Wide Edge
Surround allows the driver to utilize all of
working parts and maximize piston area
to the full potential eventually resulting in
more SPL and overall better sound
quality.

2) - Triangular Lattice

This invention includes all of the moving
parts of the speakers. These parts which
include the V.C., cone, dust-cap,
surround, bridge and spiders are
connected to each other and reinforced at
the joints. This design helps eliminate
wobbles and offsets usually caused by,
non-linear spiders, V.C.s and other
factory offset parts.

3) - Spider Ring

The HoLeeS spider is centered and
pressed between two specially designed
rings that keep the spider linear at all
times and improve suspension life.

4) - PSP Terminal (Patent Pending)

The “PSP” terminal may be one of the
most unique features on the HoLeeS.
This terminal is stylish and is extremely
easy to use. When directions are
followed any level of installer can
quickly have their amplifier hooked up
quickly. The PSP terminal allows users
to easily wire their speaker according
to their amplifiers specs.
