As a manufacturer of custom-engineered speaker drivers, our products are built to your specific acoustic and mechanical specifications. While we conduct 100% final inspection and testing before shipment to ensure zero defects, we understand that rare issues may arise. In such cases, rather than costly international returns, we offer a defect compensation program — affected units are replaced and shipped with your next order at no additional cost. Our team works closely with you to resolve any quality concerns promptly, ensuring your production stays on track and your business remains uninterrupted.

Please contact our sales team for more information on shipping options.

Yes, our speaker drivers are designed to be compatible with most industry-standard mounting formats, impedance ratings (4Ω, 8Ω), and crossover frequencies. However, for optimal performance in your specific system, we recommend consulting our technical team for custom tuning and integration support to ensure seamless compatibility.

We accept various payment methods for wholesale orders, including T/T (wire transfer), L/C (letter of credit), and D/P (documents against payment). For long-term partners, OA (open account) terms may also be available upon credit evaluation. Please contact our sales team for more information on payment options and applicable terms.

The lead time for wholesale orders varies depending on the driver type, quantity, and customization requirements. Standard models typically require 15–20 days for samples and 25–35 days for bulk orders. Custom OEM/ODM projects may take 30–45 days, including acoustic tuning and tooling validation. Please contact our sales team for a precise timeline based on your specific project.

Yes, we offer extensive customization options for our speaker drivers on wholesale orders. Our capabilities include frequency response shaping, impedance curve optimization, custom mounting formats, terminal configurations, diaphragm material selection (polyimide, titanium, textile, paper), and magnet type choices (ferrite/neodymium). We also offer custom laser engraving and retail-ready packaging with your branding. Please contact our sales team to discuss your requirements and receive a quote.

Yes, we offer samples for wholesale buyers. For standard catalog models, we provide free samples with shipping costs borne by the buyer. For custom-designed samples that require new tooling or acoustic development, a sample fee applies, which is fully refundable upon confirmation of a bulk order. Sample lead time is typically 10–15 working days. Please contact our sales team to request a sample and discuss your testing requirements.

Our minimum order quantity (MOQ) varies by product type. For standard catalog drivers, MOQ is typically 100–200 units per model. For custom OEM/ODM projects, MOQ is generally 500–1,000 units per design, depending on the complexity of tooling and acoustic development required. We understand that new product launches may require smaller initial quantities — please contact our sales team to discuss your specific needs and we will do our best to accommodate.
