Diamond Audio 6.5" HEX Series 2-Way Component Set w/25mm Silk Dome Tweeter - H65S

Unlock refined, high-end sound with the Diamond Audio H65S 6.5" 2-way component speakers, engineered for audiophile-grade car audio performance and precision sound reproduction. As part of the acclaimed HEX Series, this system delivers a perfect balance of clarity, warmth, and dynamic response, making it an ideal upgrade for serious listeners and custom audio builds.

At the core of the H65S is a 6.5-inch mid-woofer with a hard anodized black aluminum cone, designed for exceptional rigidity and fast transient response. This results in tight, accurate mid-bass and detailed midrange, allowing vocals and instruments to sound natural and lifelike across a wide range of music genres.

The system is paired with a 25mm silk dome tweeter featuring a neodymium motor, delivering smooth, extended high frequencies without harshness. This creates a warm, natural sound signature that enhances long listening sessions while maintaining excellent detail and clarity.

Built on a die-cast aluminum basket, the H65S minimizes unwanted resonance while providing superior structural strength and durability. The FEA-optimized high-power motor with a vented pole piece ensures efficient heat dissipation and consistent performance under demanding conditions.

The included model-specific adjustable crossovers allow for fine-tuning with -2dB, 0dB, and +2dB tweeter attenuation, along with a phase adjustment switch to optimize sound staging based on speaker placement. The integrated Rear Acoustic Fill (RAF) output enhances the listening experience by expanding the soundstage and improving stereo imaging.

With 75W RMS power handling, optimized sensitivity, and precision engineering, the H65S delivers clean, balanced audio performance in a wide range of installations.

The Diamond Audio H65S HEX Series speakers deliver rich, natural sound, precise imaging, and premium build quality, making them the perfect choice for those who demand refined performance and true musical accuracy in their car audio system.
