7 balanced armature drivers per channel to unleash the true fidelity of your music

The low-frequency unit adopts TRN's customized 22955 driver, which has powerful and robust output. Two customized 50060 BA drivers are used for upper-midrange and high frequencies. One customized 29689 BA driver uses for the lower-midrange and bass. Three customized 30095 BA drivers are used for exceptional treble details. This combination gives TRN X7 a full, sweet, and yet highly resolving sound.
The balanced, homogeneous sound is neutral and refined with grandeur!

The highly precise 3D printing process brings out beautiful beyond our imagination

TRN X7 utilizes DLP (Digital Light Processing) 3D printing - an exact 3D printing technology with impeccable accuracy. Every structural detail is more finely reproduced, especially the internal acoustic chamber, which is difficult to achieve with conventional 3D printing.

A simple yet effective crossover system

TRN X7 inside schematic
TRN X7 uses a 3-channel independent sound duct with an individual chamber to obtain a purer sound and crosstalk between multiple BAs. With the help of precision 3D printing, all 7 drivers will better maximize their strength.

Professional audio system electronics are mounted on SMT surface mount PCB. This design provides excellent electrical characteristics of the crossover network.
