AD-1864PD AVENGER – 18” 4800W Ultra High-Power Subwoofer

Meet the Audiotone AD-1864PD AVENGER – 18” 4800W Ultra High-Power Subwoofer built to dominate large-scale audio environments with its extreme power, precision, and durability. Designed for pro audio applications such as touring systems, concerts, mega-events, and high-end club installations, this speaker delivers unmatched performance in deep bass and low-frequency reinforcement.

With a peak power handling capacity of 4800W and a robust 2400W RMS rating, the AD-1864PD AVENGER is made for serious power demands. It features a massive 135mm (5.5”) In/Out voice coil, engineered for superior heat dissipation, greater control, and high-efficiency output. This advanced coil design ensures the speaker can handle sustained high volumes with minimal distortion and maximum clarity.

With a sensitivity rating of 97.5 ± 2dB, the AD-1864PD AVENGER delivers efficient and powerful sound output. It performs exceptionally well across a wide frequency range of 35Hz to 2500Hz. From deep sub-bass to strong low-mid tones, this driver ensures smooth and punchy audio reproduction. It’s an ideal choice for live sound engineers and system integrators seeking both power and precision.

The AD-1864PD AVENGER is built for durability and long-term performance. Its heavy-duty aluminium basket ensures solid structural support and helps minimize unwanted mechanical resonance. A powerful Y35 magnet (280×140×25 mm) enhances magnetic flux, boosting motor strength and sound control. Together, these components deliver improved efficiency, better responsiveness, and enhanced overall sound quality.

With a nominal diameter of 18” (460 mm), this driver is capable of large air displacement, ensuring impactful low-end presence. The 8-ohm impedance and 5.8-ohm DC resistance allow seamless compatibility with most professional amplifiers and crossover systems, while the net weight of 22.4 kg makes it a heavy-duty choice for fixed or rugged touring use.

FAQ Section

1. What is the benefit of checking the acoustic phase alignment when adding this 1800W subwoofer to an existing sound system?

When deploying a high-output subwoofer like the Avenger alongside your main mid-high speaker cabinets, checking the acoustic phase alignment is critical. If the subwoofer’s cone moves backward at the exact instant your top cabinets’ cones move forward, their sound waves will cancel each other out at the crossover point.

2. Why does an amplifier’s “dampening factor” matter so much when driving a heavy-duty 18-inch woofer cone?

The dampening factor is an amplifier’s capability to control the physical movement of a speaker cone after the audio signal stops. An 18-inch touring-grade cone assembly has significant physical mass; when hit with a heavy bass note, it wants to keep moving due to momentum.

3. How do thick rubber isolation feet on a subwoofer cabinet improve real-world sound quality at a venue?

An 1800W RMS subwoofer creates extreme mechanical energy that transmits directly into whatever surface the cabinet is sitting on. Placing heavy-duty, high-density rubber isolation feet on the bottom of the enclosure breaks this mechanical connection. It prevents the wooden box from vibrating against hard concrete floors or hollow wooden stages.

4. What thickness or gauge of speaker cable should be used to wire this high-power transducer?

Because this subwoofer draws immense electrical current from the amplifier, using speaker cables that are too thin will cause electrical resistance, heating up the wire and wasting power. For a short run under 25 feet, a heavy-duty 14 AWG (2.5 $mm^2$) cable is the minimum recommended size.

5. What are the best practices for safely stacking multiple heavy subwoofer enclosures at a festival?

When stacking multiple large subwoofer boxes to create a bass wall, safety and stability are paramount. Always ensure the ground surface is completely flat, solid, and capable of supporting several hundred kilograms. Use the integrated interlocking foot recesses built into the cabinets so the top boxes lock securely into the ones beneath them.
