If you're looking for truly explosive bass tones, check out the Black 18S. This professional active subwoofer from Alto Pro's Black series neatly reproduces the lower frequencies and is suited for fixed installations as well as mobile applications. An 18-inch woofer and 2,400 watts of peak power ensure an excellent performance, and the subwoofer can easily be combined with a 12 or 15-inch satellite speaker. The Alto Pro Black 18S has another card up its sleeve, though: wireless connectivity.

Wireless control

A downloadable app for iPhone and iPad enables you to wirelessly operate the Black 18S. Delay, compression and equalizer settings can be easily adjusted, and it is also possible to wirelessly stream music from your iOS device. Operating a speaker has never been this easy - simply control the immense power of the 18S subwoofer with a touch of your screen.

Tough, rugged and powerful

The rugged Alto Pro Black 18S active subwoofer is equipped with a durable cabinet. Various controls and connectors can be found on the rear panel of the active sub. The speaker has been developed to endure even the most demanding circumstances, and a scratch-proof finish protects the 18S from getting damaged during transport. All features of this tough Alto Pro active subwoofer, from its high-grade woofer components to its steel-reinforced feet, have been designed for great durability and power.
