Product details

The Pro-Ject Speaker Box 3 E Carbon is a compact 2-way bookshelf speaker that sets new standards in the HiFi and home theater world. With its impressive performance, this speaker delivers precise bass and a detailed acoustic stage that has rarely been achieved in this size category. The combination of cutting-edge technology, high-quality materials, and elegant design makes it the ideal choice for music lovers and movie fans. The speaker is equipped with a 3-inch bass/midrange driver, whose carbon fiber diaphragm offers exceptional stiffness at minimal weight, reducing unwanted distortion. A 0.75-inch silk dome tweeter ensures fine high-frequency reproduction. The resonance-free MDF cabinet minimizes sound coloration and guarantees clear and transparent playback. The bass reflex design enhances the frequency range of low tones and allows for an impressive sound volume that is disproportionate to the compact size of the speaker.

  • 3-inch bass/midrange driver with carbon fiber diaphragm for reduced distortion
  • 0.75-inch silk dome tweeter for precise high-frequency reproduction
  • Resonance-free MDF cabinet for clear sound reproduction
  • Bass reflex design to enhance low frequencies
  • Versatile for near-field applications, home theater, or as discreet speakers.
