Professional stage speakers with high and low split frequency. The appearance design is clean and reasonable, feel the shock sound of the stage,Add frequency point adjustable switch. Adjustable 2800HZ-2900Hz to meet different needs,Bass high temperature resistance and high inductance. Treble 41mm/ bass 66mm large skeleton,Self-recovery protection with PTC. Hf porcelain cement resistors and weld-free terminals,Import MKP anti-interference capacitor. MKP is "metallized polypropylene film capacitor", metallized material loss is small, high anti-interference, small internal temperature rise, and excellent flame retardant performance, is a powerful of high performance frequency divider Rare shockproof effect. The four corners of the circuit board are equipped with shockproof feet, easy to install, all components are fixed with high temperature glue, no matter how big the vibration can not affect the operation of the divider Model: -2507 (high/Low split frequency) Filter characteristics: high and low Frequency point: 2800-2900Hz adjustable Power: 300w Suitable impedance: 4-8 ohms Application: stage/home speaker high and low modification and upgrading Conversion method of capacitor AC and DC: 180-200AC=400DC 250AC=450DC-500DC 300AC=600DC Colour:Photo Color Material:PCB Package Contents: 1 x Audio Speaker Crossover Only the above package content, other products are not included.
