DLS RC3 – Compact and Well-Performing 3-Inch Coaxial Speaker for Rich Sound
The DLS RC3 is a coaxial speaker that combines high-quality materials and meticulously designed components to deliver a detailed and balanced audio experience. With its compact size and adaptable design, the RC3 is an excellent choice for car enthusiasts looking to optimize their sound system without compromising space. The 3-inch treated wood fiber cone, paired with the integrated silk dome tweeter, provides impressive sound reproduction with clear midrange and smooth high tones.
Designed for low distortion and linear performance, the speaker features a Nomex® spider and NBR suspension, ensuring controlled cone movement. A durable aluminum basket minimizes unwanted resonances, while the copper shorting ring reduces magnetic distortion for more defined sound output.
Features and Benefits:
- Treated Wood Fiber Cone: Lightweight and responsive for natural sound reproduction.
- 0.5" Silk Dome Tweeter: Perfectly balanced treble reproduction that complements the midrange.
- Nomex® Spider and NBR Suspension: Ensures low distortion and long-lasting performance.
- Copper Shorting Ring: Enhances distortion and inductance performance.
- Anti-Resonant Aluminum Basket: Reduces vibrations and increases durability.
- Compact Design: Fits easily into tight spaces within the car’s interior.
