“The passive crossover network passed our ISO‑13485 audit on first try – a rarity for Chinese suppliers.” – Dr. Emily Chen, Biomedical Engineer, MedTech Solutions.
All products are backed by CE, FCC, RoHS, GS, CB, VDE, SAA, ISO 9001, and HACCP/GMP certifications.
Active crossovers use digital signal processing (DSP) before amplification, offering precise frequency division and adjustable slopes. Passive crossovers split the signal after amplification using inductors, capacitors, and resistors, which is simpler but less flexible.
Yes. Our R&D team can tailor both active DSP parameters and passive L‑C network values to meet any target crossover point (20 Hz‑20 kHz) and slope (6 dB‑24 dB per octave).
Active crossovers: 1,000 units; Passive crossovers: 2,000 units. For sample evaluation we ship 10–20 units free of charge.
We offer DDP (Delivered Duty Paid) to the USA, EU, and Canada. All shipments include commercial invoices, CE/ FCC test reports, and HS codes to ensure smooth clearance.
A dedicated account manager, 24/7 technical hotline, and a 12‑month warranty covering material defects. Firmware updates for active units are provided free of charge.
