  • 64 Audio Twelve Ti - Limited Edition

    The TWELVE Ti marks nearly a decade of U12t dominance, now encased in a specialised titanium suit for those who find standard aluminium a bit too "common". Utilising medical-grade Ti-6Al-4V for the shells and faceplates, this edition offers exceptional strength-to-weight performance and bio-harmony. It’s the ultimate commemorative piece, blending a legendary acoustic profile with a material built to outlast the competition.

    The 12-driver internal architecture remains a masterclass in precision, utilising patented tia and LID technologies to ensure consistent, transparent sound across any device. A 4-way passive crossover balances the deep lows and crystalline highs, while the apex venting system intelligently alleviates ear-canal pressure. It’s designed to eliminate listener fatigue, providing a vast soundstage that feels as open as a premium studio monitor.

    Available for a limited time, the TWELVE Ti comes bundled with a bespoke silver-plated copper shielded cable for a seamless "head-to-toe" titanium aesthetic. The kit is exhaustive, including multiple apex modules and a full array of SpinFit and TrueFidelity tips to guarantee a perfect seal. It’s a complete professional package for the audiophile who wants the best of 64 Audio’s history in one box.

    Aerospace-Grade Titanium
    The TWELVE Ti features shells and faceplates crafted from Grade 5 (Ti-6Al-4V) titanium, a material prized in aerospace for its strength-to-weight ratio. This choice ensures the monitors are virtually indestructible yet remain exceptionally light for long-term wear.

    A Decade of the U12t Legacy
    This special edition commemorates nearly ten years of the U12t’s global success, refreshed with a specialised titanium aesthetic. It blends the legendary acoustic performance of the original with a premium finish designed for those who demand ultimate durability.

    Patented tia™ Tubeless Audio
    By eliminating traditional sound tubes, the tia™ system allows high frequencies to radiate directly into the ear canal via a single-bore design. This significantly reduces resonance and distortion, delivering a crystalline, lifelike transparency that conventional IEMs simply cannot replicate.

    apex® Pressure Relief
    The Air Pressure Exchange (apex) system vents trapped air pressure from a sealed ear canal, preserving standard isolation while removing listener fatigue. This allows for a much wider soundstage and a more natural listening experience during long studio sessions.

    Linear Impedance Design (LID)
    Our patented LID circuit ensures that the TWELVE Ti sounds consistent regardless of the source device. It corrects the varying electrical resistance of the 12-driver array, maintaining the intended sound signature whether you’re using a smartphone or a high-end DAC.

    High-Performance 12-Driver Array
    Inside each shell is a sophisticated 12-driver configuration, balanced by an integrated 4-way passive crossover. This setup provides deep, authoritative lows, rich mids, and sparkling highs, making it a reliable reference tool for both mixing and critical listening.
