Frequently Asked Questions

The MOQ for standard catalog drivers is 1 piece. Our MOQs are flexible — pricing is quantity-driven, so larger orders attract better unit prices.

Yes. OEM and customized versions typically require higher MOQs, driven by the minimum purchase quantities of the raw materials and components involved.

Yes. Each product has its own MOQ, and for catalog products that MOQ is exactly 1 — so you can combine any mix of catalog models in a single order.

Yes. You can buy directly from us, or through our distributors and online retailers. For single pieces, shipping directly from the factory may not be the most economical option — a distributor or retailer in your region is often the better route. See the contact page for our distributor list.

Both. We sell directly and through regional sales representatives and distributors. The contact page lists our offices, representatives, and distributors by region.

We aim to hold most catalog items in stock. Larger quantities may need to be built to order.

We run several operational modes to match your purchasing pattern: pure make-to-order (no stock guarantee), negotiated buffer-stock levels, and forecast-driven production. For recurring demand, an agreed buffer stock or rolling forecast can shorten and stabilize lead times.

Samples are paid. Contact us by email — or through the contact form, choosing "Request samples or a quotation" — with the product codes and quantities you need.

About 3 days for stocked items and about 25 days for non-stocked items.

Any quantity you require.

Not directly. We may credit the difference between the higher sample price and the production unit price once a production order is placed.

It depends on the product. Some modifications (for example impedance) are possible; others require extended engineering work. Contact us with your specific request and we will confirm what is feasible.

Certainly. We collect extensive measurement data from every sample and from production builds — T/S parameters, frequency response, impedance curves, and Klippel data — and can provide it along with your samples.

45 calendar days.

Production lead time is 45 calendar days. For a new project, add the design and validation phase up front — its duration depends on the complexity of the design.

Typically EXW or FOB Shenzhen. For OEM customers, shipping terms are negotiable — we can work with whichever Incoterm suits your logistics.

Yes — we ship worldwide. We can arrange freight for you, or work with your preferred forwarder.

Yes, no problem — we do this very often.

Packaging depends on the product and quantity. Contact us with the specific model and volume and we will calculate cartons, pallet dimensions, and weights precisely.

Capacity varies with driver size and complexity; on average around 8,000 drivers per day.

Recommended retail pricing (RRP/MSRP) is available from our online retailers or on request. For project and volume pricing, contact us with the models and quantities you need.

Yes. Quantity discounts vary per model — ask for a quotation at your target volumes.

We are very flexible on payment terms — whether T/T, L/C, deposit-based, or net terms, contact us with your specific requirements.

USD or RMB.

60 days.

Tooling and NRE apply to custom developments that need dedicated tools. The range is wide: simple tools can cost as little as a few tens of dollars, while complex injection tools can exceed $50,000. NRE charges are refunded against placed production orders.

We follow a well-established development process: sample builds (S1…Sn), followed by engineering, design, and production validation stages (EVT, DVT, PVT), and then mass production (MP). Each stage has defined deliverables, milestones, and decision points. Customers and partners get full access to our project-management tools — data, schedules, and risk analysis — through our software backbone.

The more detail, the better: target specifications, response targets, enclosure constraints, drawings — whatever you have. You can attach drawings and specification files directly to the contact form (choose "Develop an OEM/ODM product"). Complete inputs let our engineering team evaluate the request properly, let our commercial team quote accurately, and prevent mistakes downstream.

It can be as fast as 60 days; the current average is around 6 months, depending on complexity.

We charge NRE for custom development, and we refund the NRE against placed production orders.

Tooling: if you invest in the tools, jigs, and fixtures, they are fully yours and under your control. Design IP follows the origin of the design: if you provide a complete design, the IP is yours; if we design the product fully, the IP is ours; where we collaborate on the design, ownership is agreed case by case.

Yes, no problem — exclusivity is standard practice with our OEM partners. Where exclusivity is agreed, your design is not offered to anyone else.

Of course. Send us yours, or we can provide our standard NDA.

There is no single number — it depends on many variables: whether the product shares parts with an existing design, whether it requires special technology, and whether it is positioned as high-volume/low-cost or low-volume/high-performance. Contact us with your project and we will advise honestly whether custom development makes sense.

Yes. Send us the datasheet or measurement data of the driver you like and we will check whether we have a counterpart available, or tell you what it would take to design something similar. A 100% performance match — especially a 1:1 match of SPL and THD — is rather difficult, but we will be upfront about how close we can get.

Yes. Contact us with your request.

Standard drivers come as they are, but we offer impedance variants. Modifications beyond impedance — connectors, cones, cosmetics — move the project into an OEM partnership, where far more is possible.

Yes — we certainly can, and we do so daily.

2, 4, 8, and 16 Ω on catalog drivers; any impedance as needed on OEM designs.

Yes. We have comprehensive design capabilities and can tune Fs, Qts, BL, Xmax, and other parameters to your targets.

We supply the full range: individual parts, electronic sub-assemblies, and complete audio systems.

We test 100% of production: every driver gets an end-of-line audio test (Klippel QC or SoundCheck QC), a listening test, and a visual inspection. In addition, two randomly selected drivers from every production batch undergo a 48-hour Klippel power test.

We are IATF 16949 certified and TÜV audited, and we regularly undergo audits by our OEM partners.

Our baseline rating is AES power, measured per the AES2 standard (2-hour test with band-limited noise). Continuous power is rated at 2× the AES power, and peak power at 4× the AES power. The same convention applies across the whole catalog.

Broken-in. Drivers are broken in with 2 hours at full power, followed by a 12-hour cool-down, before the T/S parameters are captured.

Full Klippel and SoundCheck output — either as raw KDBX files, or converted and uploaded to our website for you.

We test 100% of production at end-of-line, so we do not rely on sampling for functional quality. Outgoing audits follow standard AQL sampling practice, and acceptance criteria can be aligned with your incoming-inspection requirements.

We have 100% traceability. Every driver carries a QR code or barcode that traces it back through all manufacturing steps, components, and raw-material data.

Yes — our products comply with the applicable regulatory requirements, and we can provide test reports from accredited laboratories.

Yes.

Yes — the door is always open, and we encourage everyone to visit us.

Yes.

A 3-year limited warranty under policy RC-WAR-001. The full policy text is published at redcatt.net/warranty.

Use the structured claim form at redcatt.net/warranty-claim — it collects the product details, defect description, and photos our QC team needs. Please do not return any product before an RMA has been issued.

Yes. Where reconing a driver is economically feasible, recone kits are available.

Yes. All our products can be repaired, either directly by us or by our partners.

Four reasons. You work directly with the factory: we design and build the drivers ourselves — no trading-company layer between you and the people making your product. Engineering transparency: full T/S parameters, datasheets, 2D drawings, 3D STEP files, and recommended enclosures are published for every product, every driver is 100% tested at end-of-line, and each unit is traceable down to its components and raw materials. Flexibility: MOQ of 1 on catalog drivers, impedance variants, and full custom OEM/ODM development when you need it. Accountability: IATF 16949 certified, TÜV audited, and a published 3-year limited warranty. Combining international engineering with our own manufacturing gives you a strong price-to-performance advantage.

We are not the oldest name in the industry — some driver manufacturers have been building for forty or sixty years. We see our age as an advantage: we are young, driven, and built our products and operations from a clean sheet, without the legacy structures that decades of history often bring — overheads that, in the end, the customer pays for. And more than a decade in an industry this fiercely competitive is itself evidence that we have something to offer.

We are the actual manufacturer. Our factory is in Dongguan, China; see the contact page for addresses, and the about page for the company story.

Our factory comprises a 2,600 m² facility with an 11,000 m² expansion, running 5 production lines for drivers and 2 lines for complete audio systems. Average capacity is about 8,000 drivers per day, with a headcount of around 200 people.

REDCATT has been designing and manufacturing loudspeakers since 2014.

Most of our OEM partners are under NDA, so we cannot name them publicly. But think of ten well-known professional audio brands — we likely supply six of them.

Yes — we have localized customer support. Our US headquarters and regional sales representatives for North America and EMEA are listed on the contact page.

Every product page includes the full specification table, a PDF datasheet, 2D drawings, and 3D STEP files under Downloads. Start at the product catalog.

Codes follow a fixed scheme: category – size – design number – impedance – packaging – version. Example DR-15-004-8R-B2-C0001: DR = loudspeaker driver (CD = compression driver), 15 = nominal size in inches, 004 = design number, 8R = 8 Ω nominal impedance (coaxials show both sections, e.g. 4R8R = 4 Ω LF + 8 Ω HF), B2 = packaging code (retail packaging), C0001 = the standard REDCATT catalog version. The full code is the stable identifier — always quote it when ordering or requesting support.

The main difference is weight and bulk: neodymium motors are lighter and more compact than their ferrite counterparts. Acoustic performance can be designed to match in either technology, so the choice usually comes down to the weight budget and dimensions of your product.

Start with the filters on the product catalog — driver type, size, magnet, impedance, plus engineering ranges for AES power, sensitivity, Fs, Qts, Xmax, depth, weight, and voice-coil diameter — and the comparison guide. In the catalog you can also tick "+ Compare" on up to 5 drivers to see their full specifications side by side, export the comparison, and request a quote for the shortlist. Every product page carries the full T/S parameters and a recommended enclosure to check against your design constraints. If you are still unsure, contact us with your requirements through the contact form ("Find a standard driver").

Yes — calculated enclosure recommendations are published as part of the specifications on each product page. Use them as general guidance, and contact us if your application needs engineering support.
