Description
For musicians, audio engineers, and audiophiles who demand reference-level detail, the 64 Audio U12t delivers immersive spatial imaging across a 12-driver balanced armature array. Housed in a T6061 aluminum shell with an electroformed stainless steel faceplate, these universal-fit monitors combine the tia™ tubeless driver architecture with patented Apex™ pressure-relief modules and LID™ impedance compensation for consistent performance across any source. The 10 Hz–20 kHz frequency response and 12.6 Ω impedance make them easy to drive while maintaining the clarity that Sound on Sound described as wonderfully transparent. Community reviewers on Head-Fi praise the precision bass and treble balance, while noting that the swappable m15 and m20 Apex modules let you fine-tune the tonal character to your preference. Each pair ships with the Pearl Premium Cable featuring both 3.5mm single-ended and 4.4mm balanced connectors, three tip materials in multiple sizes, and a premium leather carrying case.
This is an open-box demonstration unit with minor cosmetic signs of handling. Please contact us for current photos and confirmation of included accessories, packaging, and warranty coverage.
