Features: Ohmic interfaces precise matching: supports 4Ω/8Ω impedance adaptation, reduce contact resistance, ensuring clear and stable transmission between the amplifiers and speaker unit. Double channel division of high and low frequencies: Build in second-order division networking, adjustable division point (typical value of 2.5kHz-3kHz), achieving a smooth transition of -3dB between high and low frequency signal, avoiding frequency band overlapping distortions. Integrated junction box design: It integrates solderless terminals block and anti shortcircuit protections covers, supports quick insertion and installation, and simplifies the DIY modification process. HIFI level component configuration: using metal film capacitors, and large power resistors, with a frequency response ranges of 20Hz-20kHz and total harmonical distortions ≤ 0.5%. Large power: 300W power coverage, suitable for home speaker, car modification and other scenario.
