INTRODUCING

7 Balanced Armature Drivers + 2 Electrostatic Drivers

True 7-way crossover

Portable, high fidelity music has never been better.


STORM, short for Subtonic Opus Reference Monitor, is designed with a simple goal in mind: to emulate a studio main monitor experience in an in-ear monitor. STORM features deep reaching yet clean bass that emulates room gain and features an incredibly detailed and accurate midrange complete with breathtaking treble reproduction.

 

Designed with 7 Balanced Armature (BA) Drivers and 2 Electrostatic (EST) Drivers in an incredibly complex true 7-way crossover, the STORM delivers unparalleled reference-class tonality and resolution befitting of its status as Subtonic’s reference monitor.


The Problem With IEMs

IEMs have traditionally been designed to be used as mere monitors for the musician to hear what they sound like on stage or for consumers to listen to music in a portable format. As a result, compromises are often made as users are not demanding extreme performance in IEMs.

Additionally, IEMs on the market face these issues:

  1. Uneven frequency response leading to unnatural sounding peaks and dips in audio playback
  2. Tuning is intentionally held back so that a ‘higher-end’ model can be released subsequently
  3. Treble response sounds odd compared to a good speaker

 

We are frustrated with the current state of the IEM market. Hence, we chose to design the STORM with an unlimited R&D budget & time so that we can create the final authority on a true high-fidelity IEM.

The STORM is intentionally designed to emulate studio monitor mains, which are used to produce the very music that we all listen to and consume daily. Why bother emulating anything else other than the very source of music?

 

Through 2 continuous years of working solely on the STORM, we are ready to present the ultimate IEM made in collaboration with our manufacturing partners, Symphonium Audio.

Why Emulate A Speaker?


It’s Not About What Drivers We Use,

It’s About How We Use Them.

The new Sonion EST Driver technology is a modern breakthrough in miniature tweeters, allowing for improved treble extension when implemented properly. However, due to the EST’s low output, generic implementations resulted in ESTs that played much softer than the BAs they were paired with, severely hampering the full potential of the ESTs.

Advanced acoustic and electrical tuning solutions were developed to seamlessly integrate EST with BA units to ensure that the EST plays on an even field, unleashing the true potential of the ESTs and achieving a revolutionary level of treble coherency and delicacy. Expect to uncover the finest details of your recordings through the ethereal speed and radiant refinement of EST drivers implemented to their fullest in groundbreaking Subtonic style.

The STORM features a split subwoofer to achieve maximum micro and macro dynamics. Utilising Subtonic Splitwave Technology (SST), we have carefully tuned our woofer and subwoofer pair to achieve a balance of speed, dynamism and tactility never before heard and felt, from an IEM woofer. With SST, we are able to replicate the vast and dynamic experience of professional studio main monitors as closely as possible. We have redefined what is possible with IEM woofers, regardless of driver type. With bass that is as dynamic as it is versatile, experience a whole new level of IEM bass.

The STORM features extremely minimal acoustic damping to achieve maximum transient clarity. Light damping is utilised on the bass driver to create more natural perceived decay and zero damping is used on the mid and high drivers. The heavy damping typically used to control the sharp resonant peaks of balanced armature drivers has instead been replaced by a complex phased array of mid and high tweeters. This novel solution allows us to shape the frequency response without incurring the usual resolution penalties of filtering, resulting in unparalleled transparency without artificially injecting detail through fatiguing peaks or unnaturally boosted treble.

Filtered Linear Attenuation Tuning

Filtered Linear Attenuation Tuning (FLAT) technology eliminates impedance mismatch, ensuring that you listen to the same unimpeded sound regardless of the device you are using.

Subtonic Splitwave Technology

Subtonic Splitwave Technology (SST) is a proprietary method of decoupling dual driver units while maintaining phase coherency. SST allows for an unprecedented level of tuning accuracy, allowing us to achieve Subtonic's signature tonal precision.

Subtonic Crossover Technology

Subtonic Crossover Technology (SCT) optimises the frequency range each driver plays to reduce distortion and to create a highly coherent sound. We ensure that all components in the singal path are of top quality. Automotive-grade inductors, capacitors and resistors are used to intricately fine-tune our earphones, resulting in unparalled transparancy.

Extremely Extended ExtremitieS

Extremely Extended Extremities (EEE) is our assurance that linear extension to the lowest and highest audible frequencies is achieved, resulting in a full-ranged musical experience often only heard in the highest end loudspeakers. Experience bottomless bass and seemingly limitless treble extension with EEE.
