Procurement Taboo #1 ⚠️

Quality Inconsistency in Mass Production

Receiving initial golden samples that look great, but suffering from drifting specifications and failing parts in bulk delivery.

Factory Solution:

100% pre-shipment acoustic testing and strict raw material batch locking. What you test in the sample is strictly duplicated in bulk.

Procurement Taboo #2 ⚠️

Communication Delays & Technical Misalignment

Dealing with non-technical middlemen who fail to understand acoustic parameters, leading to costly tooling and sample errors.

Factory Solution:

Direct connection with senior SOHO export specialists and tooling engineers. Direct translation of technical specs with <24h feedback.

Procurement Taboo #3 ⚠️

Fragile Packaging & Transit Damage

Delicate voice coils, crossovers, and speaker diaphragms arriving deformed or ruined due to poor export packaging standards.

Factory Solution:

Reinforced multi-layer shockproof export cartons, vacuum-sealed moisture barriers, and drop-tested palletization designed for long-haul shipping.

Frequently Asked Questions

Everything you need to know about our voice coils, custom acoustic specifications, ordering, and global shipping.

For standard catalog voice coils, our MOQ is typically 50 to 100 pieces per specification. For custom-designed voice coils requiring special former dimensions or wire materials (like CCAW or silver-plated wire), we support low trial MOQs starting at 50 pcs to help emerging acoustic brands test their markets with minimal risk.

We pride ourselves on rapid prototyping. Standard custom sample production takes only 3 to 5 working days. Once completed, we dispatch them immediately via global air express (DHL, FedEx, or UPS), ensuring you receive your test samples within 3 to 6 days globally.

Unlike general trading companies that only perform random spot checks, we conduct 100% computerized sweeps on all voice coils and drivers. Every batch is tested for resonance frequency (Fo), DC impedance, SPL, and thermal endurance, backed by 4-layer anti-static and vacuum sealing protection for safe transit.

We offer flexible trade terms including FOB (Guangzhou/Shenzhen), CIF, CFR, and EXW. For shipping, we handle air express for urgent samples, regular air freight for medium batches, and cost-effective sea container consolidation (LCL/FCL) for bulk orders to Asia, Africa, and the Middle East.

You can download our standard CAD templates from our Resource Center or directly contact our senior acoustic engineering team via WhatsApp or email with your driver frame specifications. We will evaluate and reply with professional blueprints within 24 hours.
