AD-18N127YX 18-Inch High-Power

Audio professionals choose the AD-18N127YX 18-inch High -Power  subwoofer for its high efficiency and powerful, distortion-free bass performance. Designed for performance, precision, and durability, it is an ideal choice for live sound reinforcement, PA systems, concert setups, and premium car audio systems.

With a nominal RMS power of 2200W and a peak power handling of 4400W, the AD-18N127YX delivers powerful low-frequency output. It is designed to perform in demanding environments like live concerts, PA systems, and large venues. This subwoofer produces deep, tight bass with clarity, even at high volumes. Its efficient power handling ensures strong performance without distortion or overheating. Its wide frequency response range from 35Hz to 2000Hz ensures tight, clean bass and a seamless transition to mid-range frequencies.

The AD-18N127YX features a large 5-inch (127mm) in/out voice coil, designed for maximum heat resistance and efficient energy transfer. This large coil size helps reduce thermal compression and ensures consistent performance during extended operation at high volume levels.

At the core of its magnetic structure is a powerful Neodymium magnet (120×50×15mm). It delivers high magnetic flux density while keeping the weight low. Neodymium technology enables lighter speaker designs without reducing output strength. This makes the AD-18N127YX a smart choice for portable professional audio systems where weight matters.

Built with a rugged and lightweight aluminum basket, the AD-18N127YX ensures excellent structural stability and heat dissipation. Its 8-ohm nominal impedance and 5.2-ohm DC resistance offer compatibility with a wide variety of amplifiers and crossover systems, giving audio professionals greater flexibility in sound system design.

With a sensitivity rating of 98 ± 2dB, this subwoofer delivers high output even at moderate power levels, making it highly efficient in both indoor and outdoor environments. Weighing just 12.9 kg, it is easier to handle than many traditional 18-inch subwoofers with similar power ratings.

Whether you’re building a touring sound rig, upgrading your club’s low-end, or designing a high-SPL mobile setup, the AD-18N127YX offers unmatched power, performance, and reliability in a lightweight form factor.

Frequently Asked Questions

Q1: What voice coil size is used in Audiotone 21-inch subwoofers?

A: Our professional 21-inch subwoofers are engineered with elite 5-inch (127mm) or larger inside/outside copper voice coils wound onto heavy-duty glass fiber formers. This massive structural configuration provides excellent electrical handling capacity, allowing the transducer to sustain high-power operational peaks without suffering structural failure.

Q2: What type of amplifier is required to run a 21-inch high-power subwoofer?

A: To drive a 21-inch subwoofer safely, you need a high-headroom professional dual-channel amplifier capable of supplying 2500W to 3500W RMS per channel at 8 Ohms. Underpowering a massive 21-inch cone can cause severe amplifier clipping, sending a distorted square-wave signal that will quickly overheat and burn out the voice coil.

Q3: Will a 21-inch Audiotone subwoofer cause power compression during outdoor roadshows?

A: No. Audiotone 21-inch transducers feature an advanced multi-flow cooling chassis ventilation architecture. This industrial frame design uses heavy aluminum cooling channels to continuously force hot air away from the internal magnet gaps, maintaining highly stable, consistent sub-bass pressure levels even during extended outdoor sound competitions.

Q4: Where can I buy a genuine Audiotone 21-inch subwoofer with original factory support?

A: Genuine Audiotone 21-inch subwoofers can be purchased securely through our official website or via our verified nationwide network of authorized pro-audio dealer channels across India.
