Audiotone AD-1856PD PRO | 18-Inch 2400W Driver Component

If you are looking for ground-shaking bass and relentless power, the Audiotone AD-1856PD PRO is the ultimate 18 inch 2400W Driver Component. Specifically engineered for high-pressure touring systems and massive club installations, this professional sound system sets a new standard for low-frequency performance.

Extreme Power for Professional Sound

The AD-1856PD PRO is not just a speaker; it is a high-performance high-power 18-inch transducer. Designed to handle a staggering 2400W RMS and up to 4800W Peak Power, this driver delivers deep, cinematic bass that stays clean even at extreme volumes.

Why the AD-1856PD PRO Stands Out:

• Massive 5-Inch Voice Coil: Equipped with a 5 inch voice coil subwoofer design using In/Out + 4-layer technology. This allows for maximum heat dissipation and superior motor strength.

• Heavy-Duty Magnet: A massive 280mm magnet ensures tight control over the cone, resulting in precise, punchy bass without distortion.

• Extreme Sensitivity: With a 98dB sensitivity, this driver is incredibly efficient, converting raw power into massive acoustic output.

• Built Like a Tank: Weighing in at 23.6 KG (Gross Weight), the solid construction is designed to withstand the physical demands of high-SPL environments.

Technical Specifications

Professional Applications

The Audiotone AD-1856PD PRO is the heart of any high-end sound reinforcement system. It is the perfect choice for:

• Touring Sub-Bass Enclosures: Perfect for large-scale outdoor concerts and festivals.

• Nightclub Sound Systems: Delivers the consistent, heavy-duty low end required for modern electronic music.

• Cinema & Large Auditoriums: Provides the deep sub-harmonics needed for immersive audio experiences.

Upgrade Your Bass Performance

Don’t settle for average low-end. The Audiotone AD-1856PD PRO provides the reliability and “chest-thumping” power that professional sound engineers trust. With its advanced cooling and massive motor structure, it is built to outperform the competition.

FAQ Section

1. Why is an ultra-wide 5-inch (125mm) inside/outside voice coil layout crucial for a 1700W RMS subwoofer?

When an 18-inch transducer continuously processes a massive 1700W RMS load, it generates tremendous internal heat. A 5-inch voice coil provides a significantly larger surface area to dissipate this heat compared to standard smaller coils. By using an inside/outside winding design—where copper wire is wrapped on both sides of the cylinder former—thermal energy is transferred twice as fast into the surrounding metal cooling channels.

2. How does extensive internal cabinet bracing maximize the impact of this 1700W PRO subwoofer?

Because this 18-inch subwoofer delivers immense physical energy, the walls of a poorly braced wooden enclosure will flex and warp under the extreme internal air pressure. This flexing absorbs valuable acoustic energy, resulting in a noticeable loss of bass punch and introducing cabinet panel vibrations.

3. What is the aerodynamic purpose of the large rear center cooling vent on the magnet structure?

When the speaker cone travels forward and backward at high speed, it acts like a giant piston, compressing air inside the motor structure. The large center vent on the back of the magnet serves a dual purpose: it allows this trapped air to escape freely, preventing back-pressure from slowing down the voice coil’s movement, and it continuously draws cool air directly across the heated wire windings.

4. What happens when you couple two 18-inch subwoofers close together in a venue setup?

Placing two identical 18-inch subwoofers directly next to each other creates a phenomenon known as acoustic coupling. When the cabinets are touching or within close proximity, their sound waves merge and act as a single, much larger acoustic source. visually and physically, this coupling grants a free acoustic bonus—boosting your low-end output by up to +3dB without requiring any extra power from your amplifiers.

5. How does long-term usage affect a speaker’s impedance, and how should an amplifier compensate?

As a subwoofer runs hard during a long concert, its voice coil temperature rises, causing a natural phenomenon known as impedance rise or impedance drift. The heated copper wire naturally increases in electrical resistance, meaning a nominal 8-ohm speaker might resistance-shift significantly higher. This shift forces the power amplifier to deliver less effective wattage over time.
