82FHM is mid-woofer driver, designed for hi-fi, studio monitors and outdoor applications. Design sports hard-anodized aluminum cone and dustcap. These two key components extend the working range of the woofer. The parameters were optimized for usage in sealed enclosures. All metal parts are coated to further increase weatherized protection, surround has UV stabilizers. Strong aluminum basket was used in this design which further improves the mechanical fatigue and allow the speaker to be used in demanding portable products. Further more, we have developed new magnetic circuit for this model. Our clever engineering takes the best balance between the performance and cost. Rest assure we have FEM optimized air-venting of this design that minimizes the air-noise and greatly improves voice coil winding venting.
