Eleven multi-driver configurations support the magnificent and immersive staging
MACBETH is committed to fully reproducing the rich emotional expression hidden in music, using 5 balanced armature (BA) drivers, 4 electrostatic (EST) drivers, and 2 bone conduction (BC) drivers. Based on dual bone conduction, it achieves a grand yet harmonious and immersive staging.
5-Way Crossover for Sophisticated Sound Balance
Precise integrated control of the 5-way crossover for 11 carefully tuned drivers, including Low (DiabloBA), Mids (BA), Mids Highs (BC), Highs (BA), and Super Highs (EST), with FCR.
Acoustic Resonance Chamber (ARC): Acoustic Resonance Technology that Draws Out the True Essence of Sound
Our proprietary "ARC," which utilizes the principles of acoustic engineering, is an innovative resonant space technology precisely designed to maximize the acoustic characteristics of the driver. It is constructed using a precisely calculated resonant chamber, and is meticulously designed so that the driver, especially the core driver, interacts with the chamber to draw out its acoustic potential and create space for harmonic vibrations. This achieves an immersive sound that is faithful to the original source. By properly resonating the vibrations produced by each driver, it adds rich harmonics and natural reverberation to the sound, dramatically improving the expressive power of music.
High-precision Crossover Circuit "Forte Circuitry Relay (FCR)"
Equipped with FCR, a proprietary crossover circuit that provides perfect control over all drivers. It completely controls all electrical signals and electrical relays. By optimizing the characteristics of each driver, compensating for weaknesses, and amplifying strengths, it creates a perfectly harmonious sound profile across all frequency bands. The integrating FCR meticulously arranges components such as resistors and inductors, carefully constructing circuits that stimulate or suppress the operation of each driver. This approach ensures that all drivers in our IEMs serve their precise purpose and contribute to the overall sound profile. Furthermore, a key element of FCR is its use of some rare vintage parts, production of which ceased in the 1990s. Combining rare and valuable parts with core drivers achieves an extremely organic and realistic sound image in terms of mid-range and tonal reproducibility. This meticulously designed circuit balances the overall acoustic sound, creating a sense of realism as if the performance were unfolding right before your eyes.
Proprietary Diablo Driver
The "Diablo" is a completely original balanced armature ultra-low frequency reproduction bass-specific driver jointly developed by Forté Ears and Sonion. Developed to achieve "extremely realistic and deep ultra-low frequency expression" as requested during the prototype development stage, this custom driver boasts an astonishing ultra-low frequency reproduction capability down to 10Hz, enabling organic and powerful bass sounds. Furthermore, the synergistic effect with our proprietary FCR circuit prevents bleeding and enhances overall realism, reproducing the natural expanse and power of a pipe organ resounding in a concert hall, while also providing speed and agility.
Fully integrated multi-driver architecture
The frequency range where bone conduction drivers are most effective is the mid-to-upper mid-range, where human hearing is most sensitive. This frequency range is crucial as it covers the majority of instrument and vocal sounds. By focusing the bone conduction driver on this range, we meticulously planned the entire driver architecture to allow users to fully enjoy the rich, nuanced, and immersive sound produced by this driver. To cover the full frequency range from 10Hz to 45kHz, optimized BA and EST drivers were placed in areas not covered by the bone conduction driver. The system was carefully designed to form a complete system without phase cancellation or a cramped feeling, ensuring seamless and harmonious operation.
Fusing one-of-a-kind drivers
The innovativeness of Forté Ears is also evident in the drivers developed through skilled techniques. To achieve the desired sound, we carefully select core drivers, both new and old, for each model. Based on extensive experience, these drivers are refined and finely tuned to ensure that every product delivers unique and exceptional sound quality.
Rare Vintage Components Offering Unique Characteristics
Rare vintage components, carefully procured and selected, play a crucial role in fine-tuning and enhancing the overall sound. The vintage components used in the FCR circuit, due to their scarcity, provide unparalleled tuning quality, and when combined with the core driver, exhibit unique acoustic characteristics not found in modern parts. They especially lend exquisite depth and realism to the expressiveness of the mid-range. Furthermore, when combined with the dual bone conduction drivers, they create an extremely organic and realistic representation of the mid-range and timbre.
Ergonomic body design for enhanced fit and immersion
While adopting a tribrid configuration, the shell shape has been thoroughly optimized for extended listening. The ergonomic design enhances the seal with the ear canal, naturally enveloping the entire ear when worn, achieving both excellent sound isolation and comfort. Furthermore, the internal structure, which compactly houses the driver units and resonance chamber while maintaining a clear vibration path for the bone conduction driver, minimizes interference with the fit. Additionally, by optimally distributing the center of gravity within the ear canal, stress from cable pull and changes in posture is reduced. This allows for rich detail expression in the mid-to-high frequencies while suppressing the feeling of burden on the outer ear.
A Symphonia of Faceplate Colors
Featuring an artistic rhodium-plated pure copper faceplate crafted by hand. By skillfully incorporating the physical properties of the material, which harness the plate's resonance, it plays a crucial role not only as a design element but also in the tuning process.
Eletech-manufactured cable for MACBETH, supporting ultimate sound quality
An ELETECH OCC Copper Litz cable with superior touch noise resistance and handling, complementing MACBETH's sound characteristics. ELETECH's original design and sophisticated parts not only enhance the sound characteristics but also elevate the artistic world view embodied by MACBETH to an unwavering level.
