The Sub Box 50 E measures 20.5 cm wide, 28 cm high and 20.5 cm deep, and weighs 6 kg. Its 130 mm driver fires downwards from a sealed cabinet. Pro-Ject designed it to fill a living room with dynamic bass despite its small size.
The built-in amplifier delivers 50 W RMS and 100 W peak. Frequency response runs from 38 Hz to 160 Hz at -3 dB. The signal-to-noise ratio reaches 72 dB and THD+N stays at 0.015% at 1 W.
The metal rear panel groups stereo or mono RCA inputs and stereo or mono high level speaker terminals. The high level input lets you connect it to the output of a power amplifier. The crossover frequency adjusts continuously from 65 to 150 Hz, and a phase inversion switch helps it blend with the speakers.
In automatic mode, the subwoofer switches on as soon as a signal reaches an input and goes to standby after 10 minutes without signal. It then draws 0.4 W, against 101 W at full power. Its rigid MDF cabinet comes in high gloss black or white.
