The Pro-Ject Speaker Box 12 E Carbon speakers are made in a 2.5-band configuration and feature an inch tweeter with a silk dome, which, according to the manufacturer, should provide transparent, natural high-frequency sound. This tweeter works with two low-frequency speakers with diffusers made of carbon composite material with a diameter of 16.5 cm.
The compactness of the new product in comparison with the older model is due to the use of midrange/woofer speakers with carbon fiber diffusers with a diameter of 10 cm, while the Pro-Ject Speaker Box 12 E Carbon speakers are equipped with speakers with diffusers with a diameter of 16.5 cm. All models of the line have the same tweeters, with a 2.5 cm diameter silk dome.
The Pro-Ject Speaker Box 12 E Carbon is a 2.5-way speaker system featuring a 1-inch silk dome tweeter, which the manufacturer claims should deliver clear high frequencies. This tweeter works with two 16.5 cm carbon composite woofers.
Like the top-level model 12, the Pro-Ject Speaker Box 10 E Carbon speakers are designed as a 2.5-way system operating in a phase-inverted design with a port located on the rear wall of the case. The crossover is made on discrete elements and provides a flat frequency response.
