Based on scientific architecture
Let each frequency band directly reach purity
Redefine the precision and authenticity of sound
Electronic frequency division (also known as active frequency division or front-end frequency division) divides the audio signal before power amplification, accurately segmenting high, medium, and low frequencies for low-power signals, and then driving the corresponding speaker unit through an independent amplifier. Compared to traditional power division (passive division), it completely solves acoustic pain points with a more scientific architecture
EN30 integrates lossless frequency division, precise control, optimized phase, and improved damping. Through flexible 2/3 output switching, precise frequency division point selection, independent high, medium, and low frequency volume and phase adjustment, you can customize the optimal frequency division scheme according to the characteristics of different speaker units and listening environments, fully unleash the potential of speakers, obtain flatter frequency response curves, clearer transient responses, more accurate sound field positioning, and ultimately present satisfactory pure, natural, and dynamic high fidelity sound quality.
