High-Precision 3D Printed Acoustic Tube Structure
The first technology is the acoustic crossover tube. It uses physical frequency division to adjust the sound frequency response of the pair. It has been fine-tuned and optimized to harmonize the sound waves from different tubes. This eliminates the peaks caused by the resonance of the unit under traditional frequency division technology.
