In environments where bass response can make or break the overall sound quality, the ULT18 offers uncompromising power and control.

One of the core strengths of the ULT18 lies in its advanced Class-D amplifier delivering a total of 1000 watts of low-frequency power through two bridged channels. This means you get strong, distortion-free bass output capable of filling large venues or adding weight to professional studio mixes without the need for an external amplifier. The 18-inch ferrite woofer with a 4-inch voice coil is engineered to handle high excursion and deliver tight, accurate low-end performance. This translates into fuller, richer bass that enhances music, speech, and effects with precision and authority.

The subwoofer’s audio controls provide practical tools to tailor its output to your specific needs. With adjustable output level, low pass filter, and preset select functions, you can easily optimize the subwoofer to complement your main speakers and room acoustics. The ability to invert polarity and switch between mono and stereo modes adds further flexibility, ensuring seamless integration into a variety of audio setups. For users, this means a subwoofer that can adapt to different environments and sound systems, delivering consistent performance without complicated manual adjustments.

Constructed from durable 15 mm eucalyptus plywood and protected by a powder-coated steel grille, the ULT18 is built to withstand the rigors of frequent transport and heavy use. Its robust cabinet design not only ensures longevity but also minimizes resonances that can color the sound. The inclusion of two side handles enhances portability, making it easier for audio professionals and event technicians to move and set up the subwoofer quickly. Additionally, ground-stack provisions and a pole socket make it versatile for various stage configurations and sound reinforcement setups.

In terms of connections, the ULT18 offers two line inputs with 10 kΩ impedance, supporting a maximum input level of +22 dBu. This makes it compatible with a wide range of mixers and audio sources, providing flexibility in how you integrate it into your existing system. The output section features two XLR male connectors for mix out and direct out, facilitating easy daisy-chaining or additional system routing without signal loss. The voltage requirements spanning 100-240 VAC at 50-60 Hz make it suitable for international use, a valuable feature for touring professionals.

Measuring 25 inches wide, 22.5 inches high, and 24.5 inches deep, the ULT18 is compact enough to fit into most stage and studio setups without sacrificing performance. Its crossover frequency is set at 90 Hz, which means it effectively handles bass frequencies while allowing your main speakers to focus on mids and highs, resulting in balanced and clear overall sound. This combination of size, power, and control makes the Presonus ULT18 ideal for live musicians, DJs, sound engineers, and studio professionals who demand reliable, high-quality bass reproduction.
