XDEC (Shenzhen Xuanda Electronics Co., Ltd.) has been specializing in speaker manufacturing for 17 years, serving customers in over 30 countries. When selecting a speaker supplier, buyers mainly care about: stable lead time, flexible MOQ, and consistent batch quality. This article shares practical insights from the factory side.
Full range speaker drivers are the core components for smart speakers, soundbars, and home theaters. The 4-inch size (Φ100mm, approximately 4 inch) is the most popular specification-it's compact, easy to match with enclosures, delivers decent bass response, and remains cost-effective. XDEC's monthly capacity reaches 2 million units, with standard items shipping in 3-5 days and custom orders in 15-20 days. We respond to technical inquiries within 24 hours.
Full Range Speaker Driver Selection: 4 Key Specifications
Choosing a full range speaker driver is straightforward-focus on 4 key specs: impedance, power, sensitivity, and frequency response. These parameters directly determine compatibility, audio quality, and cost.
| Specification | Common Range | Selection Guide |
|---|---|---|
| Impedance | 4Ω / 8Ω | 4Ω offers wider amplifier compatibility; 8Ω has slightly higher sensitivity |
| Power | 3W-50W | 5-15W for home use; 30W+ for professional applications |
| Sensitivity | 79-96dB | Higher sensitivity means less amplifier power needed |
| Frequency Response | 80Hz-20kHz | Low-end depends on F0; high-end depends on treble extension |
XDEC manufactures full range drivers from Φ10mm to Φ165mm (0.4 inch to 6.5 inch), supports OEM/ODM customization, and provides free datasheets and test reports.
2 Inch Full Range Speaker Driver Procurement: Too Small to Work?
Many buyers think 2 inch (Φ50mm or smaller) drivers can't produce decent bass. Actually, 2-inch units are hot sellers for smart speakers and smart displays-they're compact, require minimal enclosure volume, and consume low power. For a Φ50mm (2 inch) full range driver, the practical MOQ path is 500 pcs for pilot runs to verify consistency, then 3,000 pcs for standard mass production.
When selecting 2-inch drivers, watch out for two issues: F0 shouldn't be too low (below 150Hz requires large enclosures), and sensitivity must be high enough (above 84dB), otherwise the sound feels muffled. XDEC's 2-inch drivers maintain F0 between 180-250Hz with sensitivity at 85-90dB, balancing size and sound quality.
Custom Speaker Driver: How to Specify Parameters?
The first step in customization isn't drawing blueprints-it's specifying parameters. Your parameter sheet to the factory must clearly state: dimension, impedance, power, sensitivity target, frequency response target, and mounting method. These five items give the factory the foundation for structural and magnetic circuit design.
| Parameter Category | Required | Optional |
|---|---|---|
| Dimension | OD × Height | Cutout size |
| Electrical | Impedance, Rated Power | Max Power, Impedance Tolerance |
| Acoustic | Sensitivity, Frequency Response | F0, THD |
| Mechanical | Mounting Method | IP Rating |
XDEC provides free parameter review, with feedback within 48 hours, helping you avoid specification errors and rework.
Speaker Driver Procurement: Lead Time and MOQ Negotiation
The two most common buyer questions: Can I order less? How long for delivery?
| Order Type | MOQ | Lead Time | Notes |
|---|---|---|---|
| Pilot Run | 500 pcs | 7 days | Consistency verification |
| Standard | 3,000 pcs | 3-5 days | Stock availability |
| Custom | 10,000 pcs | 15-20 days | Mold making + pilot run |
XDEC's lead times are fast in the industry. Standard items ship in 3-5 days from stock. Custom orders take 15-20 days for first article, with mass production starting at 30 days. Rush orders are possible with additional fees.
Speaker Driver Factory Evaluation: 3 Things You Must Check
Don't just visit the showroom-check three critical areas: IQC department, testing lab, and warehouse.
IQC department shows shipping standards-good factories match drivers within ±1dB, not the default ±3dB. Testing lab shows measurement capability- whether they have AP audio analyzers and anechoic chambers, which directly affects parameter accuracy. Warehouse shows inventory depth-how many SKUs they stock and whether they have buffer capacity, which determines lead time stability.
XDEC holds ISO9001 and IATF16949 dual certification, with 17 years of manufacturing standards. Our driver matching tolerance is ±1dB, leading the industry in batch consistency.
FAQ: Speaker Driver Procurement FAQ
| Question | Answer |
|---|---|
| Full range vs. coaxial speakers: which is better? | Depends on application. Full range drivers have simple structure and lower cost, suitable for smart speakers where extreme audio quality isn't required. Coaxial speakers offer better sound quality but need multiple drivers and crossover networks, increasing cost. |
| 4Ω or 8Ω: how to choose? | The amplifier decides everything. D-class amplifiers recommend 4Ω; AB-class amplifiers work with 8Ω. Mismatched impedance can cause power issues. |
| Are samples free? | Regular specs: 1-2 pcs free sample. Custom specs: sample cost charged, refunded on bulk order. |
| What certifications do you have? | ISO9001, IATF16949, TUV, CE, ROHS-17 years of export experience, serving customers in Germany, Japan, Korea, USA, and Southeast Asia. |
| Can MOQ be negotiated? | Pilot runs start at 500 pcs, standard orders at 3,000 pcs, custom at 10,000 pcs. Long-term cooperation qualifies for volume discounts. |
