ELFINEAR Myth II Monitoring Unit Parameters and Acoustic Effect Mapping
(April 23, 2025, 11:27 | Technological Parameter Precision Restoration Version)
I. Core Parameter Upgrades and Acoustic Logic
1. High-frequency Optimization(Adjustment in the 4kHz-6kHz Range)
- Technical Realization:
- Diaphragm Coating: A ring-shaped silicone damping layer is coated on the surface of the titanium diaphragm to absorb the lateral vibration energy.
- Magnetic Circuit Optimization: The spacing of N45 magnets is compressed to reduce the magnetic flux distortion in the 5kHz frequency band.
- Effect Examples:
- Vocal Sibilance: The sibilance of the word "breathing" (at 6kHz) in Faye Wong's "Sky" decays naturally without harsh and prickly sounds.
- String Harmonics: When the E string of the violin is vibratoed, the continuity of the harmonic series in the range of 4.5kHz-5.5kHz is improved, simulating the on-site listening experience.
2. Effective Frequency Extension to 8kHz
- Structural Support:
- The diameter of the rear cavity vent hole is reduced and the air permeability is decreased by 40%, enhancing the mid-frequency density.
- A spiral flow guiding pattern is added to the inner wall of the vent hole, extending the air flow passing time to 1.8ms.
- Perceptual Improvement:
- Percussion Details: The 8kHz harmonics of the ride cymbal in a jazz drum can distinguish the difference between a 20cm and a 30cm diameter cymbal.
- Analysis of Electronic Timbres: The high-frequency modulation tracks of synthesizer sound effects (such as the square wave harmonics of Chiptune) are clearer.

5. Key Data Mapping
Parameter Before Upgrade (Myth) After Upgrade (Myth II) Examples of Listening Feeling Differences
Peak-to-valley Fluctuation at 4kHz ±2.5dB ±1.2dB The smoothness of the transition in the coloratura of a soprano's singing is improved.
Energy Attenuation Rate at 8kHz -9dB/oct -6dB/oct The sense of airiness of the harp's harmonics is extended by 0.5 seconds.
Transient Distortion (TMD) 1% 0.7% The layering and separation degree of the full orchestra's unison in a large-scale symphony are optimized.
Summary: This upgrade strictly follows the principle of "physical sound tuning first". By suppressing harmful vibrations with a silicone damping ring, reconstructing the ventilation structure to regulate the acoustic characteristics of the cavity to achieve precise frequency response adjustment, the "parameter upgrade" is transformed into perceivable sound value. For example, when playing back Ryuichi Sakamoto's "Async" album, it can not only capture the extremely high-frequency current noise (above 8kHz) of the synthesizer but also maintain the warm texture of the piano's mid-frequency - this is precisely the innovative significance of Myth II as a professional monitoring tool.
