Eric Johnson and Eminence Design The Perfect Speaker
“Vintage alnico tone for the purist in you. Designed from the past with the future in mind…”- Eminence website about the EJ1250.
Eminence, an industry leader in the manufacture of professional audio gear since 1966, has provided musical instrument loudspeakers for some of the finest electric guitar amplifiers in the world, including Fender. Take a look inside the 15 watt Blues Junior and you’ll see an Eminence label stuck directly on the back of the speaker. That’s merely one of many famous amps that employ the Eminence brand inside.
Now, legendary guitar whiz, vocalist and songwriter Eric Johnson, a noted Fender man, has joined with Eminence in producing a new guitar speaker, the Signature Series EJ1250.
First, about the company
Eminence, the loudspeaker producer, borrowed its name from the City of Eminence, located in Henry County, Kentucky. Eminence the company, which uses the slogan, “The Art & Science of Sound,” is still located in the vicinity of its namesake town, over on Mulberry Pike. Company tours are available.
The Eminence website provides a bit of background about the company:
“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 maintain three 18″ speakers per day, based on a commitment from Ampeg’s Everett Hull…the company’s capacity has grown to over 10,000 speakers per day, employing nearly 200 people.”
Bob Gault (10/2/25 – 10/4/02) handed the reigns over to his son Rob who maintains his father’s business philosophy.
Now, about the speaker
Whether the guitar set-up is purely vintage vacuum tubes or contemporary virtual modeling, the sound still has to come out of the speaker. Among other things, the diameter of the cone, the weight of the magnet, its power rating and construction materials are some of the factors that affect the character of a speaker’s sound.
For those looking to recone an existing amplifier or the electric six-stringer who may be seeking a fresh tone, the EJ1250 guitar speaker may just be the answer. Considering how Eric Johnson, a noted Fender player, advocates using an Eminence EJ1250, one can’t help but wonder if the product is best suited to handle “Uncle Leo’s” celebrated spring reverb and vintage clean resonance.
According to Eric Johnson, referring to the EJ1250 online, “I’m excited that for the first time in many years there’s a new speaker that I love the sound of.”
And finally – the specs
The American built EJ1250 guitar speaker sports a 12″ diameter, 35 oz. alnico magnet and a 1.75″ voice coil. It is power rated at 50W. Normal impedance is at 8 ohms with a usable frequency range of 80Hz – 5.1 kHz.
The speaker makes use of copper in the voice coil and a paper cone. The magnet is made of alnico, an acronym for “iron alloys,” in this case, a combination of non-corroding metals considered to be better than ceramic parts, which are cheaper to produce and frequently used by competitors.
Sealed or vented enclosures are acceptable for these cones.
Prospective buyers can purchase the Eminence EJ1250 from a number of popular e-tailers or from an authorized dealer. The EJ1250 debuted at the 2012 Winter NAMM Show in Anaheim, California; pricing is not yet available.
