Description

Built for the Lowest Notes That Matter

If you want bass that shows up when most subs fall off, the Captivator 4000ULF is built for that job. With dual 18-inch drivers in a low-tuned bass-reflex cabinet, it delivers real weight down where sound turns physical. It hits hard, stays composed, and doesn’t blur when scenes get heavy.

Power That Keeps Its Grip

A 4000 W RMS DSP-controlled amplifier gives you the headroom to push without sag. The huge slot port keeps airflow clean so output stays strong instead of compressed. You get deep pressure with control, not boom.

Heavy Build, Easy to Dial In

The cabinet is thick Baltic birch with heavy bracing, so vibration stays out of the picture. Everything fires forward for flexible placement. With XLR and RCA inputs, auto turn-on, trigger support, and LF adjust, setup is straightforward and predictable.

Key Features

  • Dual 18-inch high-excursion drivers

  • 4000 W RMS Class-D amplifier with DSP

  • Bass-reflex design tuned for very deep output

  • Strong in-room performance into single digits

  • Large slot port to reduce turbulence

  • Front-firing cabinet for flexible placement

  • Balanced XLR and RCA connectivity

  • Heavy Baltic birch cabinet construction

Sub-10 Hz Output That Shows Up

This sub goes deeper than most for real infrasonic output that you feel, not just hear. The dual eighteen-inch design and low tune point let it move serious air below 20 Hz without flopping around.

DSP Keeps It Practical

The built-in DSP with auto input and low noise floor keeps response clean and consistent. Even when you’re pushing big levels, you don’t get the distortion or harshness some big subs show.

Built to Fit Real Systems

With its heavy cabinet, front-firing layout, and multiple input options, the 4000ULF integrates into real theaters without a lot of guesswork. It stays quietly out of the way while delivering the kind of low-end power that changes the way a room feels.
