Designed for professional sound reinforcement, live performances, DJ setups, and high-end audio installations, this subwoofer brings unmatched depth and definition to your bass.

The AD-18SW115ES delivers 3600W peak power and 1800W RMS, making it ideal for high-demand audio environments. It easily handles powerful, extended bass without distortion. A robust 114.5mm (4.5″) in/out voice coil drives this performance. It offers excellent heat dissipation to prevent overheating. This improves long-term reliability, even during continuous operation. The large voice coil delivers fast, responsive sound. It also maintains consistent output at high volumes over extended periods.

Its sensitivity of 98 ± 2dB makes it extremely efficient, producing loud and clean output with minimal power consumption. The wide frequency response of 35Hz to 2000Hz delivers deep, earth-shaking bass with clarity. It also handles mid-bass tones with precision, making the subwoofer ideal for both music and sound effects.

A powerful N45-grade neodymium magnet (105×50×15) ensures accurate cone control and reduced distortion, delivering tight, punchy bass with precision. The aluminum basket provides a strong, vibration-free frame that’s both lightweight and durable, supporting professional-level performance in portable and fixed setups.

With a nominal impedance of 8Ω and DC resistance of 5.3Ω, the AD-18SW115ES integrates easily with most amplifiers and sound systems. Despite its size, the subwoofer weighs just 11.0 kg, making it easier to transport and install than traditional 18″ models.

For professionals who demand extreme power, high sensitivity, and extended frequency response in a lightweight frame, the AD-18SW115ES delivers unbeatable performance.

FAQ Section

1. What are the sound performance advantages of an N45 neodymium magnet structure in 18-inch subwoofers?

An N45-grade neodymium magnet offers a drastically stronger magnetic flux density compared to traditional, heavy ferrite rings. This concentrated magnetic force gives the motor assembly instant, rigid mechanical control over the speaker cone, yielding faster transient response and incredibly tight, punchy low-end tracking.

2. How much power can the Audiotone AD-18SW115ES subwoofer handle during large live events?

The Audiotone AD-18SW115ES is an absolute tour-grade powerhouse, engineered to effortlessly sustain a continuous 1800W RMS of nominal power handling. With a staggering peak capacity of 3600W continuous maximum power, it delivers massive dynamic headroom, ensuring that outdoor music festivals, large club floors.

3. Why is an enterprise-class 4.5-inch inside/outside wound voice coil essential for extreme bass?

A 4.5-inch (114.5mm) inside/outside wound voice coil features copper wiring wrapped around both surfaces of the internal coil former. This dual-layer architecture effectively doubles the total surface area exposed to structural airflow, accelerating thermal dissipation. By mitigating extreme heat accumulation, it safely prevents thermal power compression and prevents voice coil burnout during extended, high-volume operation.

4. Is the Audiotone AD-18SW115ES subwoofer easy to manage for mobile sound rental teams?

Yes, its portability is one of its standout commercial features. By using an advanced N45 neodymium motor and a structural die-cast aluminum basket frame, the Audiotone AD-18SW115ES weighs only 11.0 kg. This makes it significantly lighter and easier to lift than traditional 18-inch ferrite subwoofers (which often exceed 20 kg), vastly streamlining transport and enclosure installation for mobile DJ setups.

5. What sub-bass frequency response range is ideal for an outdoor concert subwoofer system?

A high-performance pro-audio subwoofer should comfortably extend down to an acoustic frequency curve of 35Hz and climb up to 2000Hz. This ultra-wide operational range enables the speaker to reproduce room-shaking sub-bass frequencies and heavy electronic low-end drops, while retaining the upper-bass precision required to seamlessly crossover with main line array top boxes.
