FAQ
A: Recommended for use with Class-D amplifier, 4Ω/2W~3W output. Most compact Bluetooth modules (CSR/BES solutions) can drive it directly.
A: Φ28mm is a small-to-medium size. Recommended rear cavity volume ≥15cc with a port tube for better bass. If enclosure design is not possible, consider our BOX-type speaker.
A: Yes. Impedance, power, sensitivity, and lead wire length can be customized. Submit your specification and we'll evaluate lead time and MOQ.
A: Yes. Submit a datasheet or contact us directly for free sample. 7-day delivery.
A: Yes. We can add waterproof coating or sealing gasket upon request, up to IP65 rating depending on application.
