FAQ
Frequently asked questions
Straight answers about our products, manufacturing and how to buy.
Products
What do you manufacture?
Subwoofers, coaxial speakers, midranges, full-range drivers, tweeters, compression drivers and components (raw drivers, baskets, cones and accessories). Everything is built in our own factory in Ningbo, China.
Do you sell to individuals?
Our focus is B2B — brands, distributors and installers worldwide. The catalog shows our range; for pricing, request a quote and we’ll come back with factory-direct terms.
Where can I see full specifications?
Every product page lists size, impedance, power handling (RMS and max), sensitivity, frequency response and mounting depth. For test reports or data sheets, email us.
Do you offer a warranty?
Yes — every model ships with a 12-month warranty against manufacturing defects.
OEM & ODM
Can you build a product to my specification?
Yes. That’s our core business. We customize cone design, magnet type, voice coil, impedance, power handling, branding and packaging. Share your target spec and volume and we’ll confirm feasibility.
What’s the difference between OEM and ODM?
OEM = we manufacture an existing design under your brand. ODM = we design something new together, tailored to your acoustic and commercial targets.
What’s the typical lead time?
Around one month for OEM mass production from sample approval. Samples usually take 1–2 weeks. Complex tooling may add time — we’ll always confirm upfront.
Do you provide samples?
Yes. We build and ship samples for your approval before mass production. Sample costs are quoted per project.
Ordering & shipping
How do I place an order?
Request a quote via the form or email. We’ll send pricing and lead time; on your confirmation we proceed to samples (for custom work) or production (for stock items).
Where do you ship?
Worldwide, from Ningbo-Zhoushan port. Shipping cost and method depend on volume and destination — we quote door-to-door or FOB/CIF as you prefer.
What are your certifications?
Our products are manufactured to CE, RoHS and ISO standards. We’re a verified supplier and Gold Member on Made-in-China. Factory audits are welcome.
