Acceleration = Force / Mass
Strongest rare earth flux density
High temperature rare earth N48H-grade neodymium magnets are sintered, assembled, and arrayed into a patented push-pull dual-pole magnetic circuit with peak 1.8 Tesla induction.
Light as air cryogenic diaphragm
Aerospace-grade polyimide film only 1.8 microns thick is cryogenically treated in liquid nitrogen at −196 °C (−321 °F), laser-traced and dynamically tensioned into a uniform driving surface.
State-of-the-art sound
With 1500% faster acceleration and 50× more driver area than a 14 × 1.5 cm ribbon mid-tweeter, the Mini Dragons deliver direct sound with precise imaging and accurate frequency, phase, and impulse response.
Planar magnetic coherency
Compared to conventional point sources that radiate, ripple, and reflect, planar waveforms propagate coherently along the originating plane like the light of a laser beam.
Beyond the box
A dipole polar pattern inverse-phase cancels with its own backwave to reduce room reflections, eliminate diffractions, and transcend traditional box artifacts.
Fatigue free at every SPL
Unlike speakers with variable impedance curves that must be energized past a threshold to produce their band-limited response, the Mini Dragons play the same response throughout their SPL range.
SHD Studio digital preamplifier
Measured, then corrected.
Digital preamplifier and processor with Dirac Live digital room correction, DSP toolbox, Volumio network streamer, and headphone amplifier.
Custom built for Dragonfire by our friends miniDSP, the SHD Studio (“Streaming High Definition”) digital audio processor integrates a digital interface (AES-EBU / SPDIF / TOSLINK / USB), network streamer, and headphone amplifier with an Analog Devices 450 MHz SHARC DSP processor to optimize the embedded Dirac Live room correction algorithm.
Using the included UMIK-1 USB measurement microphone, SHD Studio, and Dirac Live calibration software, the frequency, phase, and impulse response of the Mini Dragon system may be measured and corrected to optimize the sound for any space.

MD-4 power amplifier
Four channels, 140 filters.
4-channel amplifier with programmable DSP and AKM Velvet A/D/A converters.
Housed in a matching anodized aluminum enclosure, the MD-4 is a hand-built globally adaptable 2-input / 4-output ADC/DAC + DSP + high capacitance Class-D amplifier (250 W RMS/channel) with balanced analog XLR and PCM SPDIF, AES/EBU, and USB streamer inputs.
