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.

Minimum Optimized Maximum Don’t

Yellow (Optimized):

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

Red (Maximum):

In this zone low-distortion and sound
quality become compromised. A
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
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.

8-Gauge Speaker Terminals

The HoleeS's 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's 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.
