From 64 Audio

Packed with an unbelievable 18 balanced armature driver per ear, the U18t 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 - just like its custom counterpart, the A18t. The A18t is preferred by critical listeners in engineering, monitoring and mixing, and audiophiles.

Each ergonomic shell is machined out of a solid piece of aluminum and finished with an elegant copper-patinated inlay on the faceplates.

Technology

U18t features the following unique technology:

Tia

The tia system is comprised of three major elements: open balanced armature tia drivers, the tia single-bore design, and tia acoustic chambers. All our Custom In-Ear Monitors with tia feature two major elements of the tia system: the tia driver and the tia single-bore design.

Tia Driver
An open balanced armature speaker design for realistic resolution and transparency. By opening a balanced armature, the diaphragm becomes fully unobstructed, reducing resonance in the IEM and allowing sound to travel more naturally to the ear.

Tia Single Bore
A huge advancement in eliminating unwanted tube resonance. The large bore itself serves as a sound-shaping chamber and aids the tia high driver in delivering a linear and coherent frequency response. The short sound path provides remarkable high-frequency extension and smoothness. The large single bore also allows for easier maintenance.

Apex

Apex, or Air Pressure Exchange, is a pneumatically interactive vent that releases air pressure in a sealed in the ear canal. Apex comes in two variations, m15 (-15dB) and m20 (-20dB).

Alleviate Listener Fatigue
When you seal a miniature speaker in an ear canal, the air inside becomes trapped. Apex relieves this air pressure, allowing the eardrum to move naturally, so you can comfortably listen longer.

Extend The Soundstage
Freely moving air extends the soundstage and provides a more natural listening experience. It also preserves bass frequencies and helps the listener distinguish individual instruments.

Hear Your Audience
Custom in-ear monitors provide amazing isolation and help you hear your mix more clearly and at lower volumes than a wedge monitor or earbuds. Apex lowers decibel levels while preserving the clarity of the sounds around you, so artists on stage can connect with their audience while protecting their hearing.

LID

LID, or Linear Impedance Design, enables a consistent, reliable sound regardless of what source. This proprietary circuit corrects the non-linear impedances of the drivers, restoring proper interaction with the source and preserving the desired sound signature. Whether you're a musician plugging into a variety of gear at different gigs or studios, or an audiophile listening from low-impedance sources, LID ensures your IEMs are delivering the desired sound signature consistently. And like all our IEMs, this model can be used with a wide range of personal audio devices as well as all hard-wired and wireless monitor systems.
