AD-18X2740YX 18-Inch Subwoofer

Audio professionals choose the AD-18X2740YX 18-inch subwoofer for its exceptional power, clarity, and durability in high-performance sound systems.Designed for live events, touring rigs, large venue installations, and club systems, this subwoofer offers extreme low-frequency performance with precision and reliability.

The AD-18X2740YX offers a powerful 2750W RMS output and a peak power capacity of 5500W. It delivers deep, punchy bass with minimal distortion—even at high volume levels. A broad frequency response of 30Hz to 1500Hz allows it to handle both sub-bass and low-midrange frequencies. This ensures richer system depth and better overall clarity.

This subwoofer features a robust 5.5-inch (135mm) in/out voice coil, built to withstand extreme heat and high SPL levels over extended use. The voice coil offers excellent thermal management, maintaining consistent performance under demanding conditions.

At its core is a heavy-duty Y35-grade magnet (300×170×50mm), delivering strong magnetic force for fast, accurate cone movement. This results in tight, responsive bass reproduction, making the AD-18X2740YX a powerful tool for bass-heavy environments. With a sensitivity rating of 98.5 ± 2dB, it provides high output with minimal power input.

The aluminum basket ensures durability, rigidity, and effective heat dissipation. It’s built to handle the physical demands of high-powered audio setups while maintaining sonic integrity. The 8-ohm nominal impedance and 5.3-ohm DC resistance allow for seamless integration with a wide range of amplifiers and crossover systems.

Despite its power, the subwoofer maintains portability with a net weight of 30.9 kg, making it suitable for both fixed and mobile setups.

Whether you’re upgrading your current system or building a high-SPL rig, the AD-18X2740YX delivers unmatched bass performance. It also offers excellent thermal stability and long-term reliability — perfect for serious audio professionals.

Frequently Asked Questions (FAQs)

1. What makes the Atomic Series different from regular DJ speakers?

The Atomic Series uses top-tier Y35-grade magnets, heavy-duty aluminum baskets, and thick in/out voice coils. This allows them to handle massive RMS loads continuously without losing structural stability or distorting the sound.

2. Can I use these subwoofers for outdoor mobile DJ setups?

Yes, absolutely. Thanks to high sensitivity ratings and rigid construction, these drivers are highly optimized for outdoor environments where long throw and impactful bass are crucial.

3. What kind of amplifier is recommended for these drivers?

You should use a high-headroom professional power amplifier that can comfortably deliver the driver’s rated RMS power at 8 ohms to prevent amplifier clipping.

4. How does the in/out voice coil design help?

The inside/outside winding structure doubles the surface area exposed to airflow. This drastically improves thermal cooling, protects the coil from burning, and maintains stable impedance over long hours.
