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 maintain three

18” speakers per day, based on a commitment

from Ampeg’s Everett Hull. Under the

leadership of Gault and most recently his son,

Rob, the company’s capacity has grown to over

10,000 speakers per day, employing nearly 200

people.

Gault was the president of Eminence from the

company’s inception until 1992. He ofﬁcially

retired in 1993, but continued to make valuable

contributions to the company. Gault passed

away on October 4, 2002.

He was 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.

Our ﬁrst facility was less than

6,000 sq. ft. and employed

around thirty people. In 1972 Eminence

Speaker moved to a new location in Shawnee

Industrial Park on Mulberry Pike where we

remain today. The facility has seen several

additions. The ﬁrst building in this location was

just less than 30,000 sq. ft., but now has

grown to include nearly 100,000 sq. ft. all

under one roof.

Engineering

Eminence engineers diligently work to satisfy

the needs of individual customers through a

custom design, or to assist in the integration

of an off-the-shelf Eminence product for their

application. Through the use of multiple design

and testing technologies along with our fused

deposition modeling rapid prototype machine,

our engineers produce as many as 2,000 hand-

built samples per year.
