Introduction
As the culmination of +40 years of research and development in planar-magnetic
manufacturing, we are confident that Dragonfire Acoustics Mini Dragons define the state-
of-the-art in full-range, near field stereo listening.
Their unique ability to coherently excite and accelerate a light-as-air planar magnetic
diaphragm translates signal-to-sound with unparalleled accuracy, precision, and mastery
of the frequency, phase, and time domains.
Fidelity
Technologically, the strongest high-temperature rare-earth N48H Neodymium magnets
are sintered, assembled, arranged, and arrayed into patented push-pull dual-pole non
ferro-magnetic circuit with an industry leading peak magnetic induction of 1.8Tesla (1.8
Wb/m2).
!
Aerospace-grade polyimide film, 1/10th as thick as a human hair, is mechanically drawn
to a less than 2-micron thickness before being laser-conductively traced, dynamically
tensioned, and cryogenically treated with liquid nitrogen at 77 Kelvin (-321 degrees
Fahrenheit, -196 degrees Celsius), to become a uniform planar-magnetic driving surface.!
Sir Isaac Newton’s second law of motion states that Force equals mass times
acceleration (F=MA).
Re-written, acceleration may be described as force divided by mass as well as the
change in velocity of an object with respect to time. !
!
The greater the inductive force of the magnetic motor structure and the lighter the weight
of the diaphragm of the driver, the greater the acceleration and change in velocity of the
sound with respect to time.!
Level
Unlike conventional tweeters and woofers which must be energized past a minimum
threshold before reproducing the full spectrum of their band-limited response, the Mini
Dragons reproduce their balanced full range (200 to 40,000 Hz) frequency response at
every SPL level within their range enabling longer and more productive fatigue-free
listening in a broader more versatile range of applications and locations.
7

Direct Sound
Sound emanating from a conventional point source propagates outwards in all
directions, diffracting and reflecting off traditional speaker cabinet enclosures and
adjacent acoustic surfaces, causing additive peaks and subtractive nulls of interference.
These reflections distort the frequency response, ruin the phase coherency and reduce
the sound clarity of the system.!
By contrast, sound emanating from a dipole planar magnetic source coherently
propagates along the axis of the originating plane like a laser beam or LED light panel –
while simultaneously completely canceling back sound waves around the speaker in the
diaphragm plane and eliminating enclosure reflections and traditional box artifacts..!
The resulting near field full-range direct sound is effortlessly delivered to the sweet spot.
Power
As an ultra-efficient purely resistive load, the Mini Dragons require only a few watts of
power to reach normal listening levels and may be driven by a wide variety of high-end
amplifiers.
For optimal performance, we recommend the Dragonfire Acoustics MD-4, a hybrid 4-input
(XLR, SPDIF, AES/EBU, USB), 4-output (280W RMS; 1kW Peak) high capacitance class D-
amplifier with integrated 192 kHz/24-bit AKM Velvet sound converters and 140 visually
programmable digital signal processing (DSP) parametric filters for advanced crossover,
mixer, EQ, delay, compression, limiting, and flexible filter design via Snowbird
Audioweaver.
For refined room correction through impulse response filtering as well as network audio
streaming services such as Tidal and Qobuz, we also recommend our partnered MiniDSP
SHD Studio Digital Preamp.
