8" | 8FHW
Ferrite Mid-Woofer
Key features:
- Mid-woofer designed for outdoor or indoor applications
- UV stabilized Polypropylene cone and rubber surround
- Components are treated to survive harsh outdoor environments
Design notes:
8FHW was designed as mid-woofer, with extended frequency response to low frequencies, as well as good extension into the mid-frequencies. All parts are intensively treated for outdoor usage, cone, surround material are with UV stabilizers. The used adhesives make sure the driver is waterproof. The cone utilizes polypropylene material and rubber surround. This combination sports sizable amounts of low frequencies and good behavior in the higher mid-frequencies.
