Mini Dragons

Strongest Rare Earth
Flux Density

F = MA

Light as Air 
 Cryogenic Diaphragm

State-of-the-Art Sound 

With 1500% faster acceleration and 50x more driver area than a 14 x 1.5 cm ribbon mid-tweeter, the Mini Dragons deliver direct sound with precise imaging & accurate frequency, phase, & 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

Light-As-Air Cryogenically Treated Diaphgram

Aerospace-grade Polyimide film only 1.8 microns thick is cryogenically treated in liquid nitrogen at -196℃ (-321℉), laser-traced and dynamically tensioned into a uniform driving surface


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

Industry-Leading Induction
1.8 Tesla Flux Density

High temperature rare earth N48H-grade Neodymium magnets are sintered, assembled, and arrayed into a patented  push-pulll dual-pole magnetic circuit with peak 1.8 Tesla induction 

SHD Studio Digital Preamplifier 

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 450MHz Share DSP processor to optimize the embedded Dirac Live Room Correction Algorithm

Using the included UMIK-1 USB Measurment Microphone, SHD Studio, and Dirac Live Calibration Software, the frequency, phase, and impulse respone of the Mini Dragon System may be measured and corrected to optimize the sound for any space.
