Unique-Bargains 2W 8 Ohm Speaker 28mm Dia 90mm Wire Pin

SKU CH-6BD5-4V8ZM

A 2 W, 8 Ω micro speaker with a 28 mm diaphragm, 16 mm magnet and 90 mm pin-ended leads for compact audio builds

  • 2W rated power drives clear audio in compact devices
  • 8 Ohm impedance matches standard amplifier outputs directly
  • 28 mm diameter fits tight enclosures and small projects
  • 90 mm wire with pin enables quick solder-free connection
  • 16 mm magnet delivers strong output from a tiny frame

Compact 28 mm driver for embedded audio

This 28 mm diameter micro speaker is built for devices that need a tiny sound source. It suits mini box speakers, music players, doorbells, computers and multimedia projects where space is limited. The clear, melodious output avoids distortion in small enclosures. Hobbyists and OEM designers can integrate it directly into custom sound-source builds.

Pin termination frees PCB space

The 90 mm wire ends in a pin connector, letting you plug the unit straight onto a board without soldering joints. Rated at 2 W and 8 Ohm, it matches low-power amplifier outputs without extra matching components. The 16 mm magnet keeps the motor structure small, leaving room for other components in tight chassis layouts. No external crossover or enclosure tuning is required for basic operation.

Steady 2 W output under continuous use

The 2 W rating describes sustained power handling rather than a peak burst figure. With a 5.5 mm depth profile, the driver dissipates heat through its metal frame during long playback sessions. Impedance remains stable at 8 Ohm across the working range, so amplifier loading stays predictable. The magnet assembly retains its flux density without thermal compression during extended duty cycles.

Questions about this item

How long can the 2 W 8 Ohm speaker run continuously before the voice coil overheats?

The 2 W rating is the continuous thermal limit; sustained signals at or above 2 W will cause the voice coil to exceed its safe temperature and risk permanent damage.

Does the 28 mm driver become audibly loud or run hot when driven at its 2 W rating all day?

At 2 W the 28 mm driver produces moderate SPL; the small 16 mm magnet and 5.5 mm depth limit heat dissipation, so the frame will become warm during extended full-power operation.

What connector or terminal must my device provide for the 90 mm pin-ended leads?

The 90 mm wires terminate in pin connectors, so your PCB or terminal block needs matching 0.1 inch pitch pin headers or solder pads to accept them.
