Pro-Ject Audio Systems
Pro-Ject Audio Systems are widely recognised as one of the finest turntable manufacturers in the world. Their mission is simply to produce the best sounding stereo analogue components at the most competitive prices possible. The current series spans a wide range of price points, with a variety of products targeted to key demographics or to accommodate the modern listener’s unique requirements.
In 2016, Pro-Ject marked their 25th anniversary year with the release of a turntable that combined traditional styling with modern technology; showing their innate ability to keep turntables fresh and interesting at a time when popularity of the vinyl format was at a previously unprecedented level. The Classic proudly sits in the middle of a multi-award winning range of turntables that manage to combine sound performance with the latest technologies and unrivalled style at every level.
Pro-Ject are also obsessed with the importance of stereo playback systems. With modern audio systems often bringing speakers either very close together or into a single enclosure, the real impact and importance of true hi-fi stereo is being lost. That’s why everything Pro-Ject create is made with pure stereo applications in mind; bringing back the true emotional importance of music to audio enthusiasts around the world.
Based in Vienna, Austria, all Pro-Ject Audio Systems turntables are made by a highly skilled workforce with great skill, care and attention in their central-European factory.

Sub Box 50 is Pro-Ject Audio System's first step into the subwoofer market. With its impressively small form-factor it fits easily into any room, but don‘t let the size fool you. The Sub Box 50 packs a powerful punch and a dynamic sound that will fill your listening experience with body and emotion.

The high quality MDF chassis is rigid and robust, while the multiple inputs let you connect the Sub Box 50 into a variety of environments. A special high level input can be used for running from a power amplifier, resulting in an even better more convincing sound, perfectly reflecting the sound character of the speakers. The crossover frequency can also be set in nine steps, adjusting to your preference.

For ultimate convenience, the automatic amplifier mode turns the subwoofer on as soon as there is a signal present on any input. It will then automatically put the subwoofer into standby mode if there hasn‘t been an active signal for 10 minutes.

The high feature set and outstanding sound quality makes the Sub Box 50 a true high-end bargain.
