Serious Punch and Power

Add exceptional punch and power to your live sound system with the PreSonus ULT18 active subwoofer. With an 18″ woofer bolstered by an impressive 4″ voice coil and driven by 1,000 watts RMS of Class D power, the ULT18 delivers powerful bass performance. Use the variable lowpass filter to match it to virtually any set of main speakers. For low-visibility operation in a permanent installation, the front-panel LED can be defeated. Complete with a polarity invert switch and dual XLR/TRS combo inputs, the PreSonus ULT18 is a versatile active subwoofer that we can recommend for a wide range of PA applications.
