Comparing Ferrite and Neodymium Speaker Drivers from Eighteen Sound – Which One is Right for You?

Choosing Eighteen Sound Speaker Drivers: Ferrite or Neodymium – Which is Right for Your System?

In professional stage and auditorium sound systems, selecting the right speaker driver directly impacts performance, reliability, and cost optimization. Eighteen Sound offers a wide range of models with ferrite and neodymium magnets, each with unique pros and cons.

1. Eighteen Sound Ferrite Drivers – Durable, Cost-Effective, Ideal for Subs and Fixed Systems

• More affordable than neodymium
• Excellent heat resistance, stable operation in harsh environments
• Capable of high power handling – perfect for subwoofers or high-power full-range speakers
• Best suited for fixed installations running continuously

• Heavier weight, less practical for portable systems

• Stage subwoofers
• Full-range speakers for auditoriums, churches
• Permanent sound systems in event centers

2. Eighteen Sound Neodymium Drivers – Lightweight, Powerful, Ideal for Line Arrays and Monitors

• Up to 50% lighter than ferrite
• Stronger magnetic force, wide frequency response
• Enhanced portability for line arrays and stage monitors
• The standard choice for professional touring systems

• Higher price point
• Requires good heat dissipation in demanding environments

• Neodymium line array speakers
• Stage monitors for performers
• High-end treble drivers for live performance

Technical Comparison: Ferrite vs. Neodymium Drivers

Eighteen Sound Driver Recommendations by Application

Conclusion: Ferrite or Neodymium – Which Eighteen Sound Driver Should You Choose?

If you prioritize cost efficiency and durability for fixed installations, ferrite is the better choice.

For lightweight, high-performance systems like touring rigs or line arrays, neodymium drivers are the optimal solution.

Many Eighteen Sound models are available in both ferrite and neodymium versions, allowing flexibility to meet specific application needs.
