Description Built for Bass That Doesn’t Back Off If you want low end that shows up and stays solid, the Captivator 4000ULF-ST 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 Holds Together 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 Dial In 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.
