• Free from carbon fiber, Kevlar, metallic and paper
resonance typically associated with other driver materials
KEY FEATURES

British engineering, integration and production
• Designed by Esoteric acoustic engineering
• Exclusive protective magnesium coatings developed in Japan
• Acoustic engineering and cabinetry by TANNOY, Ltd. U.K.
• Final manufacturing and tuning in Scotland by TANNOY, LTD. U.K.
KEY FEATURES

What are the elements required for
high performance diaphragms?
1. Low mass
High resolution / high sensitivity
Capability to reproduce extremely delicate notes
2. Fast sonic propagation
Sharp focus
True to life dynamics
TECHNOLOGY - MG DIAPHRAGM
Magnesium (Mg) is the most “sonically neutral,”
and most lightweight industrial metal known!
Mg, three times faster acoustic response rate
compared to paper cones!

What elements are required for
high performance diaphragms?
3. High rigidity
Precise piston motion
Reduced distortion
Mg, the highest rigidity among industrial metals!
4. High internal dissipation
Better resonance control / reduced coloration
crystal-clear transparency
Mg, highest internal dissipation among industrial metals!

TECHNOLOGY - MG DIAPHRAGM

TECHNOLOGY - MG DIAPHRAGM
1. Extra-thin two layer coating to protect and seal the
proprietary magnesium compound
(Organic membrane + specialized ceramic coating)
9Better anti-resonance capability without loss in sensitivity
9Protection against rust, oxidation, volatility and other
environmental influence
2. Corrugation technology
9Carefully designed resonance control technology
9Proprietary application
Esoteric acoustic engineering and exclusive Mg coating
technology produced with NIPPON KINZOKU Tokyo
Goal: Maximize Mg performance through superior
resonance control!

Impulse response characteristics
TECHNOLOGY - MG DIAPHRAGM
AL TI Mg
Conventional metal diaphragms have a very fast response rate and slow decay.
This clearly creates metallic coloration and adds resonance.
Esoteric’s Mg cone designs have a very fast decay thanks to their higher
internal dissipation and resonance control technology (Proprietary ceramic coating
and corrugation). Furthermore, Mg is acoustically neutral and “color free.”

Mg - Sonic character / basic advantages
9Higher resolution
9Ultra high sensitivity
9Exceptionally smooth response
9Crystal-clear transparency
9Sharp focus and precise imaging
Benefits:
9Delicate strings, lively
percussion
9Natural vocalizations
9Lack of coloration –
(acoustically neutral)!

THE REVIEWS
•Stereophile / Aug. 2008… “None of this technical precision was achieved by the
speakers diluting the musical message. It doesn’t get much better than that…..a
shoo-in for class A category…….. recommended components……”
•UltraAudio.com / June 2008 …“The Esoteric MG-20 has changed what I thought
was possible from a dynamic driver…”
•SoundStage Networks / May 2008…” The MG-10 possesses all of the qualities
that you might expect from a mini-monitor -- speed, articulation, transparency, tonal
accuracy, and incredible sound staging.”
•JazzTimes / Jan. 2008… “the sound was very, very solid and evidenced extreme
clarity in addition to the authoritative weight.”
•The Absolute Sound / Dec. 2007… “The MG-20 is the most musically compelling
box speaker I’ve heard to date – a perfect example of technology in the service of
music.”
•Stereophile / Oct. 2007… “Esoteric is celebrating its 20th anniversary this year.
With products like these new Mg-series speakers, it looks as if they will be around at
least another 20 years.”
