a husband, father, and grandfather. Gault was also an
avid golfer. He is greatly missed by his family, the music
industry, and the Eminence community.

In 1966 Bob Gault founded what was to become the
world’s largest loudspeaker manufacturing company after
working as an engineer for Magnavox and CTS (Chicago
Telephone Supply). Ironically, Gault started Eminence
hoping to build only three 18” speakers per day, based
on a commitment from Ampeg’s Everett Hull. Under the

Speed, quality, service and
flexibility are the essential
elements for any successful
manufacturer operating in a
global market. And as many
OEM manufacturers look
to strategically source their
components and finished
systems in locations that
are situated to maximize
efficiencies and reduce costs,
the Eminence Dongguan
factory has expanded to
meet those needs.
Today, most brands sub-contract the design and
manufacturing of their products. However, many
OEM and ODM suppliers lead to concerns with
communication, intellectual property, quality, delivery,
and service after the sale. Eminence has expanded to
meet those concerns head on through the Eminence
Cabinet Shop. Today, Eminence can take your product,
be it from your designs or simply from your concept,
through the design and documentation process,
production, certification, and on to market.

Getting a loudspeaker, amplifier, or finished system built to
your exact specifications is easier than it may seem.
Much of our success can be attributed to the Engineering teams
in our Kentucky loudspeaker factory and St. Louis systems
design center. Through the efforts of these talented individuals,
Eminence designs and builds over 2,000 loudspeaker prototypes
annually, and numerous cabinet and amplifier designs for a wide
range of professional audio and musical instrument applications.
Our team is ready to guide you through the entire process step
by step.
Contact our Sales Department at (502) 845-5622 or via email
to [email protected] to discuss your needs.

Your request will be documented and forwarded to our
Credit Department for approval. If you have not filed a
credit application, you will be afforded the opportunity
at this phase. Because we make loudspeakers for many
companies, we are frequently asked to copy another
customer’s product. Such designs are proprietary and we
strictly avoid such duplication.

Once approval has been received from our Credit
Department, your request will be forwarded to our
engineering lab or St. Louis design center for processing.
There are no design fees for the products we manufacturer
for you!
Because the prototype(s) are built to your specifications,
it will be your responsibility to thoroughly test them. Each
prototype will be shipped with a specification page and an
approval form. Once the design is approved, fax or email the
approval form back to Eminence along with your purchase
order.
Most unique loudspeaker samples are typically built and
shipped within 2 to 3 weeks.

Eminence has a wide selection of raw
materials and off-the-shelf components
for quick turn-around on your custom design.
And if your project requires sourcing of unique
components or specialized tooling, we have a vast
network of trusted suppliers who consistently meet
our high quality standards.

A Loudspeaker Chassis
We offer two basket materials – pressed steel and die cast
aluminum. While pressed steel is adequate for most applications,
die cast aluminum baskets are superior cosmetically, structurally,
and magnetically. Aluminum does not conduct the magnetic field
out of the gap thereby making the motor strength higher and the
stray magnetic field lower.
The process for obtaining a prototype is
quick and simple:
1.
loudspeaker materials
Shortly after receiving the sample, you will be sent a formal
quotation, including quantity price breaks and minimum
order quantities. Samples are priced as you receive them
unless otherwise noted. Any further modifications to the
design will require a revised quotation, such as an addition
of a logo dust cap to a loudspeaker, or a selection of a
different tolex material for a cabinet.
When you approve a sample for production, we will issue
a permanent spec number to this sample. This number will
take the place of the sample number and will be recorded
as your unique product ID for all future production.
If you have any questions concerning the
sampling process, please call us at
(502) 845-5622 or e-mail us and we will
gladly guide you through the process.

With our state-of-the-art electrocoat paint system, we can apply
a uniform coating of epoxy-acrylic paint over the entire surface
of our metal parts, including the magnetic gap, to a controlled
thickness of less than 0.001”. The electrocoat paint, unlike the
zinc plating process, simply does not corrode and the application
process is economical and extremely environmentally friendly.
(for low frequency designs), dual (for summed low frequency
and low impedance designs) and dual-parallel coils (for special
applications). Winding lengths vary from .080” (2mm) to 1.6”
(40.6mm). Standard impedances range from less than 1 ohm all
the way to 70 ohms. We also offer beryllium copper ribbon leadout or pure copper ribbon lead-out for demanding applications.
We can source coils that are beyond our manufacturing range as
your application demands.
B Cone and Surround Materials
E Spiders
The cone is usually the most important contributor to the
sound of a particular speaker and our engineers may have more
experience with cone responses than anyone else on earth. We
currently stock over 300 different cones. Cone and surround
materials are available in a wide variety and are ever changing.
Because of the ever increasing power handling demands
placed on the speaker industry, spider materials have improved
dramatically over the last ten years. Eminence stocks a wide
variety of spiders ranging in diameter from 3” (76mm) OD to
8” (203mm) OD. You can choose from a wide range of spider
materials such as cotton, poly cotton, and nomex. We offer
cup spiders, flat spiders, progressive roll spiders, and a new
generation of laminated spiders.
c Magnet Sizes
Eminence offers ferrite magnets from 15 oz. to 120 oz. We can
also multi-stack magnets for long Xmax applications. If your
design requires a low stray magnetic field, we can shield it with
bucking magnets and/or shielding pots. Eminence also offers the
option of neodymium or alnico magnets.
D Voice Coils
Eminence has developed the finest voice coils in the industry.
Nearly all Eminence Speaker voice coils incorporate a polyimide
film, specially formulated to Eminence Speaker’s specifications.
Our proprietary film offers significant advantages over other
materials including aluminum, which can conduct excessive heat
to the cone apex. Eminence voice coils are highly regarded as
structurally and thermally superior.
We currently produce 1 layer edgewound (for very high
efficiency speakers), 2 layer (for a variety of applications), 4 layer
F Terminals, Gaskets & Dust Caps
Currently, we use three basic types of terminals: 1) 0.205”/0.250”
spade connectors, 2) gold or silver colored push button terminals
with 4mm wire holes, and 3) 5-way nickel plated binding posts.
Gaskets are available in several different materials as well
as thicknesses. Speakers can have front mounted gaskets,
rear mounted gaskets, or both, depending on your mounting
configuration.
The dust cap’s major function is to keep debris or foreign
materials from entering the voice coil gap area. It also
contributes to the sound of the speaker and has become a
popular place to display product names and logos.
