REDCATT 6FHM - 8 Ohm

REDCATT 6FHM - 8 Ohm Mid-woofer

Key Features

• 3 layer cone, consisting hi-end 1k carbon fiber on nomex honeycomb core
• Fem optimized motor structure
• Low harmonic distortion

Design Notes

The 6FHM is a high efficiency, (91 dB 1watt / 1 meter) 6-inch mid-woofer with incredibly linear frequency response characteristics and ultra low harmonic distortion artifacts. The 6FHM uses a lightweight 1k carbon fiber material, assembled on both sides of Nomex honey-comb core. This unique cone provides the ideal weight to strength ratio. The rubber surround has been FEM modeled and optimized. The honeycomb cone with high-end 1k carbon fiber material provides remarkable strength, while pushing the cone break-up modes to high frequencies, significantly extending the working range of the speaker. The cone The 6FHM cone is made using 1k carbon fiber honey-comb, placed from both sides of Nomex core, while the dustcap is made off hard-anodization reinforced aluminum. The dustcap shape and the hard anodizing are further improving the mid to high frequency behavior.
