Speaker Box 15 DS2 is the flagship speaker system from Pro-Ject. The massive design of the speaker system guarantees the absence of unwanted vibrations. To increase stability, an internal cavity filled with sand is used, which also allows for better vibration absorption.
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.
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.
