Packed with an unbelievable 18 balanced armature drivers per ear, the A18t is our top-of-the-line reference in-ear monitor. This industry-first design pushes the limits of what a reference monitor can be with incredible detail, extension, and unmatched clarity across all frequencies with a powerful low-end and extended sub-bass. The A18t is preferred by critical listeners in engineering, monitoring and mixing, and audiophiles.
This model is also available as a Universal IEM, the U18t.
Exclusive technologies that challenge traditional in-ear monitor designs to give you the absolute best listening experience
A18t features the following unique technology:
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 available for A18t: mX, m15 and m20.
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. A18t features two major elements of the tia system: the tia driver and the tia single-bore design.
3D-Fit preserves the detail of your ear impressions using a new process of digital rendering and 3D-printing. The patented process of incorporating acoustical tuning features within an IEM’s shell allows for designs that would otherwise be impossible to build using traditional methods. We incorporate these advanced and uniquely complex features into the shell in order to manipulate the audio produced by the IEM. This process also reduces distortion in the impression for the most precise and comfortable custom in-ear monitors available.
