Description

Built for Bass That Shows Up

If you want low end that doesn’t disappear when things get serious, the Captivator 4000ULF-LP is built for that job. With dual 18-inch drivers in a low-tuned bass-reflex cabinet, it delivers deep pressure that you feel right away. It hits hard, stays solid, and doesn’t blur when scenes get heavy.

Power That Stays in Control

A 4000 W RMS DSP-controlled amplifier gives this sub the headroom to keep going without sag. The large slot port keeps airflow clean, so output stays strong instead of compressed. You get depth and punch together, not one at the expense of the other.

Heavy Build, Easy to Set Up

The cabinet is thick Baltic birch with heavy bracing, keeping vibration out of the picture. Everything fires forward, so placement is flexible. With XLR and RCA inputs, auto turn-on, trigger support, and LF adjust, dialing it into your room is straightforward.

Low-End Pressure That Shows Up

With its dual 18″ high-excursion drivers and reflex tuning, the 4000ULF-LP produces deep low frequencies you not only hear, but feel where it matters most. The output remains controlled instead of loose or muddy even when pushed.

DSP Keeps It Usable

The built-in DSP with auto input select and auto turn-on keeps the system clean and easy to integrate, with a lower noise floor that helps the sub stay quiet until it’s needed. You get deep output without extra hash or distortion in the midrange.

Practical Build and Placement

The thick Baltic birch cabinet with heavy bracing keeps the structure quiet under load, and the front-firing design means placement doesn’t get fussy. Between the multiple input options and LF Adjust control, it’s straightforward to dial into your room.
