The working model

How this engagement works

Our product families are manufactured in our own factory in Guangzhou. Driver and cabinet assembly, electronics, final test, ageing, packing and export loading are controlled under one quality process, so the platform, the label and the delivery schedule are confirmed directly.

That matters because the buyer is not only buying a loudspeaker. They are buying a consistent product, a document set, a warranty route and a supply plan. In-house production keeps those four under the same roof.

Questions

Frequently asked questions

The questions that usually decide the scope: loudspeaker count, amplifier size, fire interface, certification and who installs the system. If your question is not here, send it with the building data.

Ask an application engineer

Are you a factory?

Yes. We manufacture our own product families in our factory in Guangzhou, and we also provide ODM and OEM production for distributors and brands.

Can we visit the factory?

Yes, by appointment for a qualified project. The visit is subject to the production schedule and a confidentiality agreement. It is not a substitute for sample approval.

Who holds the certificate?

It depends on the model and the certification route. We confirm the holder and the scope before the order. A private label does not automatically transfer a certificate; the model-level documents are supplied with the quotation.

How do you control quality?

Through incoming inspection, in-process checks, functional test, ageing and pre-shipment inspection. The inspection level depends on the product and the order. Test records are available where agreed.

Can you supply a mixed container?

Yes, where the quantities and the packing allow it. A mixed container is planned in our factory and confirmed in the packing list. The loading plan is shared before shipment.
