Our second reinterpretation of the world renown Fourté; the first fully tubeless universal in-ear monitor. Rounding off Fourté’s industry leading legacy, Blanc delivers a fresh perspective, both cosmetically and technically. A custom designed open dynamic driver, one balanced armature, and two tia drivers challenge the technical possibilities of a four driver system. This culmination of small yet powerful details all build upon the wide resolving nature of the tia system, bringing recorded music to life.

Sound
Blanc is tuned very similarly to Fourté Noir, with some subtle improvements in the low-frequency band due to a new implementation of the dynamic driver, resulting in lower distortion. Lows reach deep while maintaining realism, giving space for upper bass and mid-range punch/presence. This accuracy in the mid band is not only a result of its own amplitude but because of the quick transient response of the high-mid section. The high-frequency band is left sounding pure and clean. Tia’s classic sound-stage presents the depth of the stereo field rather than just the width. Recordings with sudden wide panned instruments seemingly come from behind the listening position. Perception of effects and tiny details are deepened. Vocals are centered yet tucked to the back of your head, giving them space while gluing them into the mix.

Limited and minimal in nature, each Fourté Blanc is one of only 500 units; all with exclusive packaging and upgraded internal components contained within a pristine white ceramic-coated shell. Internally, everything from the driver choice and position to the solder is meticulously engineered. These are beautifully juxtaposed with the unique patina of Blanc’s copper faceplate, the cloth pattern and letter pressing on the packaging; all imperfect in their own way giving each Fourté Blanc customer a truly exclusive experience.

Air Pressure Exchange (Apex) is a patented vent that releases air pressure in a sealed ear canal all while retaining standard IEM levels of isolation; enabling music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex is integrated in Fourté Blanc all the way down to the way the shell is milled, offering similar pressure release and isolation to our m20 module.

Tubeless In-Ear Audio (tia) is a patented IEM design methodology that aims to reduce unwanted resonance and distortion for a transparent and lifelike sound signature. The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. Fourté Blanc utilizes the complete Tia system; its four drivers radiate freely into the Tia bore with no obstructions to the drivers.

Featured Technology
Rather than constricting the sound of the drivers by fitting a tube onto them, Duo’s complete Tia System reduces unwanted resonance and distortion by allowing the 9mm Dynamic Driver + Tia High Driver to radiate freely into the single large Tia bore with no obstructions to the front of the drivers.
Apex Core is a deeper understanding of air movement within an earphone system. Duo’s faceplate features a striking perforated grill that leaves the shell of the IEM open to the outside atmosphere for a less obstructed airflow resulting in an effortless reproduction of music and minimal physical fatigue.
Due to the high crossover point between the two drivers, Wave Sync was developed to ensure coherence; another industry first. By using a type of “all-pass” filter, we’re able to introduce a crossover while correcting for time without having to change the physical distance between the drivers.
