Product Detail
The PreSonus ULT18 subwoofer is an ideal partner for the PreSonus® ULT12 and ULT15, enhancing any full-range PA loudspeaker. It pumps out a strong, clear, and precise low-end punch. With 2,000 watts of Class D power and a ported, direct-radiating enclosure, it offers the detailed low-frequency performance that audio professionals love. Its custom 18-inch low-frequency transducer with a 4-inch voice coil can move 7 mm before over-excursion, pushing more air for a bigger thump. A variable lowpass filter, a rarity in this category, allows you to set the upper frequency limit. The ULT18 also has M10 fly points, ground stacking options, castor provisions, and a defeatable front-panel LED, making it perfect for both mobile and installation use. Features include an 18-inch custom woofer with a 4-inch voice coil and 7 mm driver travel, 2,000W Class D power (1,000W Program / 500W continuous), 2 XLR/¼' combo inputs with direct outputs, a variable lowpass filter, polarity invert, and a defeatable front-panel LED for low-visibility installs.

Using the PreSonus ULT18 subwoofer is easy. First, connect your audio source to the 2 XLR/¼' combo inputs. You can then use the variable lowpass filter to adjust the upper frequency limit according to your needs. The polarity invert feature can be used to fine - tune the sound. For mobile use, you can take advantage of the M10 fly points or the ground stacking provisions. If you're installing it in a place with low visibility, you can defeat the front - panel LED. When it comes to maintenance, keep the subwoofer in a dry and clean environment. Avoid exposing it to extreme temperatures or humidity. Check the connections regularly to ensure they are secure. If you notice any strange noises or performance issues, it's best to consult a professional.
