Description

Sound Barrier iLX218DSUB — Dual 18″ Active Subwoofer with Selectable Crossover

iLX218DSUB Overview

The Sound Barrier iLX218DSUB is an ultra-high-output dual 18-inch active subwoofer built for large-format sound reinforcement, touring systems, outdoor events, and venues demanding maximum low-frequency impact. Powered by a Class-D amplification platform, the iLX218DSUB delivers massive bass output with controlled response and dependable thermal performance across extended operating periods. A selectable crossover frequency switch (80Hz, 100Hz, 120Hz, or 150Hz) and 0°/180° phase switch provide the acoustic alignment flexibility required for complex multi-cabinet deployments. This subwoofer is designed for touring engineers, system integrators, and venue operators who require uncompromising low-frequency output with straightforward analog control.

The iLX218DSUB’s Full/High-Pass Filter output switch and Ground Lift switch streamline integration with top cabinets while addressing common noise issues in demanding signal environments.

Key Features

  • Dual 18-Inch Drivers — Two 18-inch woofers deliver exceptional depth, punch, and projection for high-energy music and large audience coverage
  • Class-D Amplification — High-efficiency amplifier platform provides massive output with reliable thermal management under sustained professional use
  • Selectable Crossover Frequency — Four-position switch selects 80Hz, 100Hz, 120Hz, or 150Hz crossover points to match a wide range of top cabinet configurations
  • Phase Switch (0° / 180°) — Enables proper acoustic alignment when integrating with full-range cabinets in varied deployment geometries
  • Full / High-Pass Filter Output Switch — Sends either a full-range signal or a high-pass filtered signal (above 120Hz) to connected top cabinets, eliminating the need for an external crossover in many applications
  • Ground Lift Switch — Reduces unwanted hum and noise in challenging signal environments common to large-scale live events
  • Large-Format Design — Engineered specifically for outdoor events, touring systems, and venues requiring maximum low-frequency coverage and projection

About brand
Sound Barrier was founded in 1972 by George Mederos and until the late '90s, Sound Barrier manufactured quality affordable car audio equipment. For almost 30 years Sound Barrier grew to become one the most popular brands of Car Audio equipment in the Americas and the Caribbean. As the market shifted and the demand for secondary market car audio equipment faded, Sound Barrier forged a new path to success, developing a small line of entry-level professional audio equipment. There was nothing fancy about the new line, just a few good quality amps, and speaker cabinets.
