AD-18X2125YX 18-Inch High-Power Subwoofer

The AD-18X2125YX 18-Inch High-Power Subwoofer delivers deep, powerful, and distortion-free bass for high-performance audio systems. With a nominal RMS power of 2100W and a peak power handling of 4200W, this premium-grade subwoofer provides the robust low-frequency response necessary for concerts, nightclubs, PA systems, and large-scale sound reinforcement.

The AD-18X2125YX utilizes a large 5-inch (127mm) in/out voice coil to handle high power efficiently. This large voice coil resists overheating and ensures long-lasting performance during continuous use. By managing heat efficiently, the voice coil enhances the subwoofer’s reliability and delivers cleaner sound at higher volumes.

Engineering & Performance

• Powerful Magnetics: A powerful Y35-grade magnet (measuring 280×140×25mm) lies at the heart of its structure, providing the strong magnetic force needed for precise cone movement and punchy, accurate bass output.

• Wide Frequency Range: The subwoofer covers a wide frequency range of 35Hz to 2000Hz, delivering rich low-end performance and smooth transitions into the lower midrange.

• Aluminum Basket: The aluminum basket adds durability, assists with heat dissipation, and reduces overall resonance.

• High Efficiency: With a sensitivity rating of 97 ± 2dB, the AD-18X2125YX operates with high efficiency, producing impressive sound output even at moderate input levels.

• Amplifier Compatibility: Its 8-ohm nominal impedance and 5.2-ohm DC resistance offer broad compatibility with professional amplifiers and crossover systems.

Versatile Design

Despite its solid construction, the unit maintains a manageable net weight of 20.3 kg, making it ideal for both fixed installations and professional touring setups.

Whether you are building a new sound system or upgrading your current setup, the AD-18X2125YX delivers the power, precision, and performance you need. Therefore, it stands as an excellent choice for achieving high-impact audio in any professional setting.

Frequently Asked Questions (FAQs)

Q1: What are the main specifications of the Audiotone AD-18X2125YX subwoofer?

A: The Audiotone AD-18X2125YX is an 18-inch high-performance subwoofer featuring 2100 Watts RMS continuous power handling and 4200 Watts Peak power. It operates at a nominal impedance of 8 Ohms, offers a frequency response range of 35Hz to 2000Hz, and delivers a high sensitivity rating of 97dB for maximum acoustic loudness per watt.

Q2: What type of voice coil does the Audiotone AD-18X2125YX use?

A: The Audiotone AD-18X2125YX uses an advanced 5-inch (127mm) inside/outside copper voice coil wound on a durable fiberglass former. By placing copper layers on both the interior and exterior sides of the former, the design doubles the surface area exposed to airflow, which significantly accelerates heat dissipation and prevents voice coil burnout during extended use.

Q3: How does an inside/outside voice coil prevent power compression at outdoor DJ events?

A: An inside/outside voice coil prevents power compression by rapidly channeling heat away from the speaker assembly into the surrounding air. During long outdoor DJ competitions, traditional coils heat up, increase electrical resistance, and lose volume. The double-sided winding on the AD-18X2125YX keeps operating temperatures low, ensuring a stable, hard-hitting bass punch all night without losing output efficiency.

Q4: What are the magnet and weight specifications of the AD-18X2125YX transducer?

A: The Audiotone AD-18X2125YX is built on a heavy-duty, resonance-free rigid aluminum basket frame and features a massive Y35-grade ferrite magnet measuring 280 × 140 × 25 mm. This high-grade magnetic assembly provides intense flux density for tight cone control, bringing the total net weight of the single speaker unit to 20.3 kg.

Q5: What size amplifier do I need to run a pair of Audiotone 2100W RMS subwoofers?

A: To safely drive a pair of Audiotone AD-18X2125YX subwoofers, you should use a professional power amplifier that delivers 3200 Watts to 4200 Watts per channel at 8 Ohms. Providing ample power headroom ensures the amplifier delivers clean audio transients without entering square-wave clipping, which is the primary cause of speaker failure and thermal damage.
