Pro-Ject Sub Box 50 E: Compact 130 mm Active Subwoofer
The Pro-Ject Sub Box 50 E is a compact active subwoofer designed to add deep, dynamic, and controlled bass to any stereo or home cinema system. Thanks to its small footprint and easy integration, it is an ideal solution for small to medium-sized rooms where improved low-frequency performance is desired without occupying excessive space.
Despite its compact dimensions, the Sub Box 50 E is capable of filling a room with surprisingly powerful and musical bass. It features a 130 mm down-firing woofer, a configuration that helps distribute low frequencies more evenly and naturally throughout the room.
Solid MDF Construction
The cabinet is built from high-rigidity, low-resonance MDF, specifically engineered to minimize unwanted vibrations and maintain clarity and definition in the bass even at higher listening levels.
Its elegant high-gloss black or white finish allows seamless integration into modern living environments.
Flexible Connectivity
The Pro-Ject Sub Box 50 E offers multiple connection options to adapt easily to different system configurations:
Stereo low-level RCA inputs
Mono RCA input
High-level speaker inputs
This flexibility allows it to be connected directly to power amplifiers or integrated amplifiers without a dedicated subwoofer output.
Adjustable Crossover & Smart Operation
The crossover frequency is continuously adjustable between 65 and 150 Hz, enabling precise integration with various main speakers.
An automatic power-on system activates the subwoofer when an audio signal is detected and switches it to standby mode after several minutes of inactivity, reducing energy consumption.
