40mm × 23Hmm Multimedia Speaker Driver
Desktop Bluetooth Speaker / Smart Speaker
Why Sourcing 40mm Speaker Drivers Always Hurts?
❌ Common Sourcing Pitfalls
- Sensitivity marked 90dB but actual SPL is 82dB - voice wake fails at 3m
- F0 too high (300Hz+) - desktop audio sounds thin, no body
- L/R channel mismatch ±3dB - manual re-sorting adds labor cost
- Batch inconsistency - 12% out of spec in a 10K run
- No IATF16949 - automotive / premium brand customers reject the factory
✓ XDEC 40mm Driver Solution
- 93dB ±3dB actual SPL - 3m far-field voice wake stable ≥ 96%
- F0 as low as 210Hz - full, warm desktop near-field sound
- L/R matched ±1dB at factory - no manual binning required
- AQL 0.65 inspection - long-term PPM < 800
- 17-year ISO9001 + IATF16949 dual system - passes Tier-1 audits

Sourcing FAQ
Q1: What is the MOQ for the 40mm multimedia speaker driver, and how long is the sampling lead time?
A: Standard catalog MOQ is 3,000 units. Trial / sampling run starts from 500 units, with sample lead time 3-5 days via DHL / FedEx. For custom F0 / SPL / impedance binning, the custom MOQ is 10,000 units and lead time 15-20 days. Spec sheet turnaround: 24 hours for proposal, 48 hours for parameter review.
Q2: Is 93dB sensitivity a real measured value or just nominal? How about batch consistency?
A: 93 ±3dB is the actual measured value under the standard 0.5W / 0.5M condition, 100% xlsx-tested and recorded. Production runs are AQL 0.65 inspected, and the 12-month rolling PPM is stable below 800 - significantly better than the industry 1500-2000 PPM range. Each shipment includes a 100% SPL scan report.
Q3: How is the L/R pair-matching of ±1dB done, and is there an extra charge?
A: Every catalog unit is 100% scanned at 1000Hz, then binned into A / B groups within a ±1dB SPL window, marked with different label colors. For stereo / dual-channel assemblies, simply pair A with A and B with B - no manual re-sorting required. This binning is a standard service at no extra cost. A tighter ±0.5dB binning is available as a custom option with 10,000-unit MOQ.
Q4: Can a 4Ω driver be wired directly to an 8Ω amplifier? Will it burn out?
A: It can be connected, but the amplifier output power will roughly double, and continuous full-power operation at 4Ω accelerates voice coil aging. We recommend leaving 1.5x headroom on the Class-D amplifier - for example, a 3W driver paired with a 5W amplifier. If your platform is locked to an 8Ω amplifier, the 8Ω version (XDEC-40Y08T series) is available. The full XDEC catalog supports 4Ω / 8Ω switching, and you can validate on samples before locking the spec.
Q5: Do you support OEM / ODM customization? Can the logo and packaging carry our brand?
A: Yes. 17 years of OEM / ODM experience, with 8 international brand customers on record. Logo silk-printing, back stickers, and outer carton marks can all follow your brand VI. FOB Shenzhen / Dongguan ports, both LCL and FCL supported, with stable monthly supply over 5 million units. 17-year professional speaker manufacturer, triple-system certified to ISO9001 / IATF16949 / TUV.
