In-Ear Monitor IEM Triple Speakers 22 Ohm 117dB 20Hz - 20kHz
With the Blessing2, Moondrop offers exceptional in-ear headphones with a rich and precise sound reproduction. The IEMs incorporate no less than three different drivers, each of which is responsible for the reproduction of a defined frequency range. A particularly effective triple filter allows these frequency bands to be distributed according to each transducer.
Physical 3D printed bandpass and lowpass crossover conduits, along with a resistor-capacitor crossover, form a triple hybrid crossover. Two Knowles SWFK tweeters handle the highs, a proprietary Mid-BA driver handles the mids, and a 10mm paper diaphragm dynamic driver handles the lows. This design provides smooth highs, accurate mids and deep lows for an immersive and faithful sound reproduction.
The physical crossover system of the Blessing2 includes a bandpass and a lowpass filter. The former is used to modify the response range of the bass and midrange drivers, while the latter is used to limit the Q value of the midrange and treble drivers. This particular design requires extreme precision in the manufacturing process but allows for incredible sound quality.
In order to accurately manufacture the complex structure of the Blessing2s without any errors, Moondrop enlisted the help of 3D printing company HeyGears. This partnership leverages DLP-3D printing with medical-grade UV resin to produce reliable, accurate, and robust complex-structured housings.
The Blessing2 faceplates are crafted from medical grade stainless steel using a precise CNC milling process and then brushed. Assembled with the transparent 3D printed shell, the whole set offers a beautiful aesthetic, both modern and sober.
The triple-crossover structure uses both acoustic filters and a resistive capacitor filter, preserving phase coherence across most of the audible spectrum while ensuring that each driver operates at its respective frequency. In addition, this method provides incredibly transparent and accurate reproduction.
