Dynamic Driver vs Balanced Armature: GK KUNTEN Driver Specs & Science
A deep-dive into the acoustic physics of DD and BA drivers. Learn why GK KUNTEN uses a single 10mm Super-Linear dynamic driver and when hybrid IEMs make sense.
Driver labels explain construction. They do not establish that a dynamic driver has worse treble than a BA, or that a BA cannot reproduce bass. This guide separates the operating mechanisms from the measurements needed to compare finished IEMs.
Moving-coil operation
A moving-coil dynamic driver converts current into force in a magnetic gap. The coil moves a diaphragm, which changes air pressure. Diaphragm area, mass, stiffness, suspension, magnetic field, enclosure and damping all affect its response; a material name alone cannot predict bass quality or transient behavior.
Balanced-armature operation
A balanced armature moves within a magnetic system and transfers motion to a diaphragm through a drive rod. It does not produce sound by striking the diaphragm. BA units can be designed for bass, midrange or treble, and their bores and acoustic damping affect the result. Neither metallic timbre nor a fixed bass roll-off is inherent to every BA.
GK G3 / KUNTEN / Streak
GK's current G3 manufacturer page identifies a dynamic design. The previous BA+DD description and 3.5kHz crossover claim in this article were unsupported and are withdrawn. KUNTEN is a single dynamic design; Streak is described in GK's product material as KUN dynamic plus a micro-planar tweeter. None of these configurations establishes a listening winner.

How acoustic outputs combine
In a hybrid, the drivers' acoustic outputs add in amplitude and phase. Electrical filters, natural roll-off, sound paths and damping can all shape that sum. A dip or peak may come from their interaction, but driver count alone cannot locate a crossover or diagnose a fault. GK Streak's exact crossover frequency, circuit and component values are not documented in the sources available for this article.
What would substantiate a performance comparison
An acoustic comparison needs the original traces, fixture, calibration, drive level, insertion conditions and exact units. Frequency response, distortion and channel matching are different measurements. No recoverable original GK dataset supports the former numerical accuracy or superiority claims, so those results are withdrawn rather than inferred from a driver description.
