1. Two highs, two mediums, one low, 5-way frequency to experience the shocking sound effect of the cinema. The sound shocks to every corner and the high-frequency part is clearly identifiable. 2. audio-specific capacitors use fever-grade polypropylene film capacitors. Good capacitors are the basis of good sound 3. Applicable to: 4-8 ohm speakers/power 400W 4. Bass inductance + polymer magnet to enhance the sinking of the bass, reasonable circuit + high-quality components + high cost performance = correct sound 5. 58mm inductance wire diameter 12MM, 58MM high-temperature wire inductance (external pure copper inner conductive special alloy aluminum wire) can well control the Q value and internal resistance of the inductance, so that the woofer can prevent the situation of powerlessness and meet the requirements of audiophiles.
