A18 Tzar

The 64 Audio A18 Tzar™ is the world’s first custom-fit earphone with 18 balanced armature drivers per ear. Designed for the most demanding listeners who are looking for the ultimate in reference sound, it features 8 low drivers, 8 mid drivers, and the incredibly smooth tia™ high and high-mid drivers. Sound from the low and mid drivers combines in the tia single-bore and blends with amazingly-detailed highs from the proprietary open balanced armature tia high driver. The result is an incredibly tight low end, super transparent mids, remarkable high-frequency extension, and an out-of-this-world depth and soundstage. A protective mesh covering at the end of the stem helps to keep out debris while apex™ module technology allows for customizing the sound signature and reduces air pressure inside the ear canal for fatigue-free listening. We pushed the limits with innovation and design to fit such a driver package in a custom earphone and are thrilled to finally drop this bomb on the in-ear monitor industry.

Like all 64 Audio Custom IEMs, the A18 monitors are 3D printed based on your uniquely shaped ear impressions and are fully customizable with a wide range of handcrafted finishes. They are inherently noise isolating and are designed to work with a wide range of personal audio devices including all hard-wired and wireless monitor systems.

Apex 3DFit Tia High Driver

Features

3D SOUND
By removing pneumatic pressure from the ear canal, sound is felt to be more spacious and outside the head when compared to traditional earphones.
CROSSOVER
A passive crossover network that directs frequencies to drivers that are optimized for their reproduction.
NOISE ISOLATION
The capability of the earphones to reduce ambient or stage noise when properly inserted.
DRIVER CONFIG
The configuration and arrangement of drivers per frequency band.
FREQUENCY RESPONSE
The range of frequencies that the earphone is able to produce under typical use.
IMPEDANCE
The load or resistance that the earphone will present to an amplifier. Lower resistance is much easier to drive than high resistance.
tia SINGLE-BORE
The single-bore design is a huge leap 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.
TRUE PHASE
ApexTM restores proper phase response at the eardrum by switching from pressure-based amplitude to velocity- based amplitude.
APEXTM
A revolutionary technology that eliminates pneumatic pressure that causes excessive eardrum movement.
SENSITIVITY
The Sound Pressure Level (SPL) produced per 1mW of input power. The higher the sensitivity the less power is required to drive the earphones.
