Description

Built for Bass That Shows Up Everywhere

If you want low end that doesn’t disappear when the room gets loud, the Captivator 4000ULF-TL is built for that job. With dual 18-inch drivers in a tall, low-tuned bass-reflex cabinet, it delivers deep pressure that hits right away and keeps going when scenes get heavy.

Power That Keeps Control

A 4000 W RMS DSP-controlled amplifier gives you the headroom to push without sag. The large slot port keeps airflow clean, so output stays strong instead of compressed. You get depth and punch together, not boom.

Heavy Build, Easy to Live With

The cabinet is thick Baltic birch with heavy bracing, keeping vibration 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

  • Tall cabinet for stronger low-frequency reach

  • Large slot port to reduce turbulence

Output That Goes Deep

With its dual 18″ drivers and reflex tuning, the 4000ULF-TL pushes low-frequency energy that most standard subs can’t match. You feel impact where it matters — big explosions, bass drops, and deep music passages come through with pressure that’s controlled, not mushy.

DSP Keeps It Practical

The built-in DSP with auto input and turn-on keeps response clean and predictable. Even when output gets heavy, distortion stays down and the sub doesn’t muddy the rest of your system. That makes it easier to integrate with AVRs and external amps.

Solid Build That Fits Real Rooms

The Baltic birch cabinet and front-firing design make placement simple, and the slot port keeps airflow smooth at higher output. Features like balanced inputs, trigger support, and LF adjust give you ways to tune the sub to your room and setup without guesswork.
