Woofer - Midbass
Features
1. Optimal magnetic power The motor design, optimized through Finite Element Analysis (FEA), delivers optimal magnetic power. 2. Weather-resistant cone The cone features a weather-resistant coating, making it suitable for both indoor and outdoor applications. 3. Smooth frequency response The cone—featuring an M-type cloth surround with applied damping glue—delivers a smooth frequency response. 4. Minimal compression The motor is designed with specialized ventilation to eliminate air compression and facilitate airflow for cooling purposes.
