1. Excessive Unit Cost – Most suppliers charge a premium for low‑volume orders, inflating your BOM by 15‑30%.
2. Inconsistent Frequency Response – Poorly designed crossovers lead to ±3 dB variance, causing audible distortion and customer returns.
3. Lengthy Lead Times – Traditional factories in Europe or the U.S. average 45‑60 days, disrupting production schedules.
4. Limited Customization – Off‑the‑shelf parts cannot meet specific impedance or power‑handling requirements of high‑end audio systems.
5. Regulatory Uncertainty – Lack of CE, FCC, RoHS, and ISO certifications can block market entry.
According to a 2025 Audio Industry Survey, 62 % of purchasing managers cited “high component cost” as the top barrier to launching new products.
