Description

Double the Drivers, Real Low-End Authority

If one 18 isn’t enough, the RTJ 18Sub Dual is built to step it up. This setup pairs two 18-inch subwoofer modules, giving you deeper pressure, more headroom, and bass that hits harder without turning loose. It’s the kind of low end you notice right away, especially in action scenes and bass-heavy music.

Clean Power That Stays Tight

Each 18-inch driver gets its own external amplification, which keeps output strong and controlled even when levels climb. Bass stays tight instead of bloated, and you get better consistency across the room compared to running a single sub harder than it wants to be.

Easy to Place, Easy to Scale

The compact, shallow cabinets make these subs easy to hide behind screens, stack, or integrate into a baffle wall. Run them as a matched pair, or add more later if the room calls for it. This setup is built for systems that want flexibility without giving up performance.

  • External amplification for each driver

  • Deep, controlled low-frequency output

  • 2x 18” Sub Module

  • 10hz-200hz (In Room)

  • 12 amp @ 120 volt (1/4 Power)

Twice the Output Without Mud

Upgrading from a single 18Sub to a Dual setup gives you noticeably more headroom and low-end pressure. Bass hits harder and stays cleaner instead of just turning louder — that’s a difference you can feel in big action scenes.

Deep Reach That Doesn’t Fold

With a combined amplifier configuration feeding two big 18″ drivers, this setup delivers usable output down near 10 Hz in real rooms. That means you get low bass that doesn’t just rumble — it adds real impact to effects and music.

Scales for Serious Systems

Because each sub is a discrete module with its own amp, you’ve got flexibility when connecting and tuning them. Run both for full low-end authority, or add more modules if your room demands even bigger bass.
