Alto Pro TS218S active 18-inch subwoofer

General

The Alto Pro TS218S big, bad active subwoofer has an 18-inch speaker, making it the largest in the TS2 series. It delivers 1250 watts of power and sub-low function for ultimate low frequencies. It's equipped with an EQ contour switch that allows the TS218S to generate sub-low frequencies, and enables you to invert the polarity if you want to use it as a full-range speaker. The frequency range of 35 to 95 Hz ensures more than sufficient audio dispersion. It's also very cost-efficient thanks to its integrated passive convection system!
