Diamond Audio 6.3” HEX Series 2-Way Component Set w/Silk Dome Tweeter - H600S

Experience precision, depth, and musical realism with the Diamond Audio H600S 6.3” 2-way component speaker system, engineered for audiophile-grade car audio performance. As part of the renowned HEX Series, these speakers combine advanced materials, refined engineering, and high-end craftsmanship to deliver a truly immersive in-car listening experience.

At the heart of the H600S is a 6.3-inch mid-woofer featuring Diamond Audio’s proprietary HEX composite cone technology, designed for exceptional rigidity and responsiveness. This results in tight, accurate mid-bass and detailed midrange reproduction, allowing vocals and instruments to sound natural and lifelike. The butyl rubber surround and flat progressive spider ensure long-lasting durability and consistent performance.

Complementing the mid-woofer is a 25mm silk dome tweeter, engineered to produce smooth, extended high frequencies with sparkling detail. The tweeter features ferrofluid cooling and a neodymium motor structure, enhancing power handling and ensuring clean, distortion-free highs even at elevated volume levels.

The die-cast aluminum basket provides superior structural integrity while minimizing unwanted resonance, ensuring clean and accurate sound reproduction. Paired with competition-grade external crossovers with Rear Acoustic Fill (RAF), the H600S offers precise frequency control and the ability to fine-tune your system for optimal performance.

With 85W RMS power handling, 4-ohm impedance, and a balanced sensitivity rating, these 6.3-inch component speakers are ideal for both factory upgrades and high-performance custom audio builds.

The Diamond Audio H600S HEX Series speakers deliver crystal-clear highs, precise midrange, and tight bass, making them the perfect choice for those who demand high-end sound quality, refined detail, and true musical accuracy in their car audio system.

Maintenance Tips    

• Wipe woofers, tweeters, and grilles with a soft, dry microfiber cloth.
• Keep silk dome tweeters free from dust, debris, and physical contact.
• Avoid high-pressure water and harsh chemical cleaners.
• Regularly inspect crossovers, wiring, and terminals for secure, corrosion-free connections.
• Ensure all mounting hardware remains tight to prevent vibration damage.
• Properly tune amplifier gain, EQ, and crossover settings to avoid distortion or clipping.
• Avoid prolonged high-volume playback to protect voice coils and tweeters.
• Protect components from excessive heat, moisture, and direct sunlight exposure.
• Periodically check for rattling, cone fatigue, or reduced sound clarity.
• Store vehicle in a covered, dry environment when not in use.
