Features
Aluminum Cone Technology
The black aluminum cone construction provides superior rigidity compared to traditional paper or polypropylene materials, resulting in reduced distortion and improved transient response. This advanced material choice ensures accurate reproduction of musical details while maintaining excellent power handling capabilities for dynamic passages.
Closed Chamber Tweeter Design
Unlike conventional open-basket tweeters, the Hamburg Line features a sealed chamber tweeter design that provides superior damping and control of high frequencies. This innovative approach eliminates unwanted rear wave interference, resulting in cleaner treble reproduction and improved stereo imaging in your vehicle's acoustic environment.
Professional-Grade Crossover Network
The sophisticated crossover utilizes premium components including air-cored inductors and high-quality capacitors to ensure seamless frequency division between drivers. The 12dB slopes provide excellent driver protection while maintaining phase coherency, delivering the natural, balanced sound signature that Audiocircle is renowned for.
ABS Compound Basket Construction
The magnetically and electrically inert ABS basket material eliminates unwanted magnetic interference while providing exceptional structural integrity. This advanced polymer construction ensures long-term durability under automotive conditions while maintaining precise driver alignment for consistent acoustic performance.
German Handcrafted Quality
Each speaker set is meticulously handcrafted in Germany to meet strict quality standards, representing the culmination of decades of high-end audio expertise. The manufacturing process combines traditional craftsmanship with modern materials science, ensuring every component meets audiophile-grade performance standards.
