1. Excessive Unit Cost – Most distributors charge a 30‑40 % premium for “ready‑made” crossovers, eroding profit margins.
2. Inconsistent Frequency Response – Off‑the‑shelf parts often drift ±5 dB, causing audible distortion in high‑fidelity systems.
3. Limited Adjustability – Fixed‑ratio designs force you to redesign the whole audio chain when you change speaker size or enclosure volume.
4. Long Lead Times – Overseas suppliers average 45‑60 days, delaying product launches and inventory turnover.
5. Compliance Risks – Missing CE, FCC, or RoHS certifications can halt shipments to key markets (USA, EU).
