Diamond Audio 6.5 “ HEX Series 2-Way Shallow Component Set w/Silk Dome Tweeter - H65SH

Big sound, slim footprint. The Diamond Audio H65SH 6.5" 2-way shallow component speaker system is engineered for space-restricted installations without sacrificing the premium sound quality and performance the HEX Series is known for. Perfect for cars, trucks, and custom builds with limited mounting depth, this system delivers refined, high-end audio in a compact design.

Built with a 6.5-inch shallow mount mid-woofer, the H65SH features a fiberglass reinforced cone that provides excellent rigidity and responsiveness. This results in tight, accurate mid-bass and smooth midrange performance, ensuring vocals and instruments sound natural and detailed even in tight installation environments.

Paired with a neodymium 25mm silk dome tweeter, this component set delivers smooth, extended highs with warm tonal balance and minimal listening fatigue. The silk dome design ensures a natural, musical sound signature that enhances clarity without harshness, making it ideal for long listening sessions.

With an ultra-slim mounting depth of just 1.3 inches, the H65SH is perfect for doors, dash locations, and shallow factory speaker placements where traditional speakers won’t fit. Despite its compact size, it maintains impressive output and performance with 75W RMS / 150W MAX power handling.

The included adjustable crossover network allows fine-tuning with -3dB, 0dB, and +3dB tweeter attenuation, along with a LPF/FLAT switch to optimize performance based on installation location. The integrated Rear Acoustic Fill (RAF) output expands the soundstage, creating a more immersive listening experience.

The Diamond Audio H65SH delivers premium HEX Series sound in a shallow design, making it the ideal solution for tight installations that still demand clarity, balance, and high-end audio performance.

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 direct high-pressure water and harsh chemical cleaners.
• Inspect crossovers and wiring connections regularly for tight, corrosion-free contact.
• Ensure all mounting hardware remains secure to prevent vibration-related damage.
• Properly tune amplifier gain, EQ, and crossover settings to avoid distortion.
• Avoid prolonged high-volume playback to protect tweeter and voice coil longevity.
• Keep components away from excessive heat, moisture, and direct sunlight exposure.
• Periodically check for rattling, cone damage, or reduced tweeter clarity.
• Store vehicle in a covered, dry environment when not in use.
