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)

Q1: What are the main power ratings and technical specifications of the Audiotone AD-18X2740YX subwoofer?

A: The Audiotone AD-18X2740YX is an absolute powerhouse of an 18-inch transducer designed for ultra-heavy-duty audio systems. It delivers an outstanding 2700 Watts RMS of continuous power and handles up to 5400 Watts Peak. Operating at a nominal impedance of 8 Ohms, it features a highly efficient sensitivity rating of 98dB and covers a wide low-frequency response range from 35Hz to 2000Hz.

Q2: What type of voice coil does the AD-18X2740YX use to handle 2700W RMS power?

A: To sustain extreme electrical power, the AD-18X2740YX relies on a massive 6-inch (152mm) inside/outside copper voice coil wound onto a high-grade fiberglass former. The dual-sided inside/outside winding method places copper layers on both the inner and outer surfaces of the former, doubling the area exposed to airflow. This architectural design maximizes heat transfer and helps prevent structural voice coil warping during heavy usage.

Q3: How does the N52 Neodymium magnet structure benefit this heavy-hitting subwoofer?

A: The Audiotone AD-18X2740YX features an elite, high-grade N52 Neodymium magnet structure. N52 Neodymium provides the highest magnetic energy product commercially available, delivering extreme magnetic flux density to the voice coil gap at a fraction of the weight of standard ferrite. This results in incredible cone speed, ultra-tight transient responses, and an overall reduction in weight—making rigging and transport much easier.

Q4: How does the AD-18X2740YX prevent power compression during prolonged outdoor sound events?

A: Power compression happens when heat builds up in the motor assembly, raising electrical resistance and causing a sudden drop in acoustic volume. The AD-18X2740YX stops this using its high-ventilation Neodymium motor structure paired with the 6-inch dual-sided inside/outside voice coil. The speaker pushes hot air out and draws cool air in with every stroke, maintaining high volume and a hard physical bass punch all night long.

Q5: What size professional amplifier is required to safely run the Audiotone AD-18X2740YX driver?

A: To safely drive the Audiotone AD-18X2740YX, you should use a professional power amplifier capable of delivering 4000 Watts to 5400 Watts per channel at 8 Ohms. Having substantial amplifier headroom prevents the audio signal from clipping into dangerous square waves, ensuring clean sub-bass transient reproduction and protecting your speaker components from thermal damage.
