- Second-order bass 12 dB per octave and second-order treble 12 dB per octave provide phase-compensated, clean crossovers for professional two-way speakers. - Dual protection in the signal path: a capacitor plus a resettable fuse guard the high-frequency path during demanding operation, helping prevent sudden loss of output and protecting drivers. - Solderless Zero terminal block for tool-free, solder-free wiring, enabling quicker and more reliable assembly. - High-performance two-way frequency divider: the treble path uses a polypropylene high-voltage anti-interference capacitor for smoother treble and better control of treble response. - Materials and performance: polypropylene capacitor for the treble stage, designed for high voltage and reduced interference, contributing to stable and refined high-frequency behavior. - Compatibility and use: intended for professional PA and two-way speaker systems, suitable for studio monitors and other high-performance loudspeaker installations. - Practical scenarios: - Live sound setups requiring phase-aligned crossover and tweeter protection in a two-way PA system. - Critical listening environments where adjustable treble response helps achieve balanced tonal accuracy. - Field installations or compact cabinets where quick, solder-free wiring speeds up setup.
