FATfreq x Effect Audio: Quantum

Experience a new level of control and precision with Quantum, a high-performance in-ear monitor featuring Planar Driver Technology and detachable Noah modules, allowing fine-tuned customization of Basscannon™ technology for a tailored low-frequency response. Engineered over a year of rigorous R&D, Quantum incorporates valuable feedback from discerning audiophiles & top-tier studio engineers, ensuring a sound signature that meets the highest industry standards.

Quantum’s Planar Driver Technology delivers ultra-fast transients, precise imaging, and an expansive soundstage, creating a lifelike sense of depth and space that enhances musical immersion. The tuning ensures a natural midrange, extended treble response, and a balanced, highly resolving presentation, making it ideal for both audiophiles and professionals seeking accuracy, flexibility, and dynamic realism.

One of Quantum’s key innovations is the elimination of the harsh upper treble "zing" commonly found in planar magnetic IEMs. Through our proprietary ResoFlow™ Acoustic System, which combines a precision-tuned resonator with a reverse exponential horn waveguide, we’ve achieved a smooth, natural treble extension while preserving micro-detail and air. This technology gradually guides high frequencies from the planar driver mouth through a carefully tapered acoustic pathway, ensuring a controlled and effortless treble presentation that avoids the excessive sharpness often associated with planar drivers. The result is a fatigue-free yet highly detailed listening experience, making Quantum stand out from conventional planar IEMs.

At the core of Quantum’s customizability lies the Noah Module System, an innovative modular tuning feature designed for versatile sound shaping. Included with Quantum is our newly innovated SuperStage Noah Module, the same breakthrough acoustic module used in our flagship Grand Maestro. This module expands the perceived soundstage, creating an immersive, holographic experience that places instruments and vocals with breathtaking spatial accuracy. Whether you're in the studio, on stage, or simply enjoying music, the SuperStage Noah Module transforms the listening experience by providing an unparalleled sense of openness and depth.

In collaboration with Effect Audio, a leader in premium cable innovation and technology, Quantum has been exclusively tuned with the Ares S II from Effect Audio's Signature Series II. The Ares S II is the world's first solid core 8-wire handwoven IEM cable, enhancing signal integrity and conductivity to deliver noticeable improvements in clarity and detail. Its proprietary Dual Variant QuantumCopper™ design blends two distinct types of copper, resulting in richer sub-lows, a stronger bass kick, and thick, alluring vocals. This collaboration ensures that Quantum not only delivers exceptional sound through its internal components but also benefits from the superior connectivity and acoustic enhancements provided by the Ares S II cable. The stock cable included with Quantum is the Ares S II in ConX 0.78 2-pin connectors & 4.4 balanced termination, ensuring that users experience the full potential of this meticulously engineered partnership.

(Patent Pending) Using bass chambers and acoustic damping networks, FATfreq was able to design the deepest bass ever recorded of over 30dB, expertly controlled below 150Hz with zero mid-range bleed. A FATfreq innovation pioneered and perfected for sheer bass power.
