AD-18X3155YX 18-Inch Subwoofer

The AD-18X3155YX 18-Inch Subwoofer is a powerful 18-inch subwoofer engineered for professional audio systems that demand exceptional performance, deep bass, and long-term durability. Designed for large-scale venues, touring setups, and high-output club systems, this subwoofer offers extreme low-frequency power with clean, distortion-free response.

With a nominal RMS power of 3100W and an impressive peak power handling of 6200W, the AD-18X3155YX delivers ground-shaking bass that fills any space with depth and clarity. Its frequency response range from 30Hz to 1500Hz makes it capable of delivering tight sub-bass as well as smooth low-midrange frequencies, ensuring a balanced, professional-grade sound.

This subwoofer is equipped with a large 6-inch (152mm) in/out voice coil, built to withstand high temperatures and continuous operation. The voice coil offers excellent thermal stability, allowing it to maintain consistent performance even during extended high-SPL use.

At the core of its design is a robust Y35-grade magnet (330×170×50mm), delivering high magnetic flux and precision cone movement. This results in fast, controlled bass response and greater overall efficiency. With a sensitivity rating of 98.5 ± 2dB, the AD-18X3155YX maximizes output while reducing power consumption from your amplifier.

The durable aluminum basket provides structural integrity and superior heat dissipation, making it ideal for high-performance environments. The subwoofer features an 8-ohm impedance and 5.3-ohm DC resistance, offering broad compatibility with professional amplifiers and crossover systems.

Despite its heavy-duty design, the AD-18X3155YX maintains a manageable net weight of 37.5 kg. This makes it suitable for both permanent installations and touring systems where reliability and power are essential.

If you need extreme bass, clean output, and robust construction, the AD-18X3155YX stands out as a top-tier solution for professional audio engineers and sound system designers.

Frequently Asked Questions

1. What makes an 18 inch subwoofer ideal for professional DJ setups?

An 18-inch driver provides a large cone surface area, allowing it to move massive amounts of air. This displacement is crucial for reproducing the ultra-low sub-bass frequencies (below 50Hz) effectively across large, open spaces.

2. What is the benefit of an aluminium basket over a steel one?

Aluminium baskets are highly rigid, which prevents the speaker frame from warping under heavy mechanical stress. Additionally, aluminium acts as an excellent heat sink, helping cool the motor structure much faster than pressed steel.

3. Can I use these drivers in horn-loaded or scoop enclosures?

Yes. Due to their strong magnetic structures, robust cones, and rigid builds, Atomic Series drivers can handle the high back-pressure generated inside scoop and horn-loaded enclosures.

4. Why does voice coil thermal stability matter?

As a speaker plays, electrical energy turns into heat. If a voice coil cannot dissipate this heat, its resistance rises, causing “power compression” (loss of volume) and eventual coil failure. High thermal stability keeps your sound consistent.
