    Packed with an unbelievable 18 balanced armature drivers per side, U18t is our top-of-the-line reference in-ear monitor. This industry-first design sits right at the boundary of what is physically possible in a UIEM. Released and developed alongside Fourté in 2016 it is the first IEM to integrate our patented tia technology with conventional IEM design, utilizing the tia high driver and single sound bore. This astonishingly complex system results in incredible detail, extension, and unmatched clarity across all frequencies.

    Sound

     

    "This is a fast set that is still smooth, similar to driving a V8 luxury car at 60 MPH without noticing any of the road noise or bumps."

    – VSG (TechPowerUp)

    "Overall, the U18t is 64 Audio’s more tonally balanced and linear monitor, with reference-like tuning. Like the Fourté, it outputs outstanding levels of micro-detailing, intelligibility and air to give it that signature top-end sound."

    – Smit Patel (Positive Feedback)

    "The sound results are completely convincing and meet the highest demands of stage musicians, sound engineers and audiophile music listeners without restrictions."

    – Ulf Kaiser (Headphone Check)

    U18t achieves its quick bass response, while retaining enough sub-bass amplitude, by coupling eight modified mid-drivers for the low frequency band rather than using fewer/larger drivers. Another eight low-mid drivers are required to match that amplitude in the mids. The one high-mid + one tia high driver combination became the basis for 90% of our entire product range. The extremely accurate response of U18t makes it perfect for critical audiophile listeners as well as mixing and mastering engineers. Each ergonomic shell is machined out of solid aluminum, anodized red, and finished with an elegant copper-patinated inlay on the faceplates.

    Featured Technology

    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. U18t features two major elements of the tia system: the tia driver and the tia single-bore design.

    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 musicians and music enthusiasts to listen more comfortably for longer. This venting alleviates listener fatigue and allows for a much more realistic soundstage. Apex comes in three module variations for U18t: mX, m15 and m20.

    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.
