Experience refined power and precision with the Diamond Audio H104 HEX 10" 4 ohm Dual Voice Coil Subwoofer, engineered for high-performance bass and long-term durability. Inspired by advanced technologies from the flagship HEX PRO series, this 10-inch car audio subwoofer delivers tight, musical low-frequency output with exceptional thermal management and structural strength.
The H104 is built around a rugged cast aluminum frame basket combined with a solid core aluminum radial heat sink, dramatically improving heat dissipation during high-output operation. Massive 3-inch high-temperature voice coils, wound on a treated high-strength aluminum former, allow the subwoofer to handle significant power while maintaining consistent performance and reduced distortion.
An exotic fiber weave cone, reinforced with a specially treated paper backing, ensures fast transient response and accurate bass reproduction. This design delivers punchy mid-bass impact and deep low-end extension, making the H104 ideal for both daily drivers and performance-oriented systems.
Featuring a 4-ohm dual voice coil configuration, the H104 provides flexible wiring options for amplifier matching and custom enclosure designs.
For enthusiasts seeking durable construction, advanced cooling technology, and dynamic 10-inch bass performance, the Diamond Audio H104 HEX Series subwoofer delivers clean, controlled, and powerful low-frequency output built to perform.
