2. Inconsistent audio performance. Tolerance gaps of ±10 % cause uneven bass response, leading to customer returns.
3. Lengthy lead times. Overseas shipments often take 45‑60 days, disrupting production schedules.
4. Limited customization. OEMs need specific inductance, capacitance, and PCB footprints, but most suppliers offer only “one‑size‑fits‑all”.
5. Compliance headaches. Missing CE, FCC, or RoHS certifications can stall product launch in the U.S. and EU.
