The 5 x 7 & 6 x 9 MAS size speakers are unique, inverted construction and the coaxially mounted tweeter helps with heat dissipation. Patent Pending design helps with thermal management for motorcycle applications to extract heat from the speaker through the front tweeter pod.
Diecast Aluminum tweeter housing draws thermal build-up away from the internal hidden neodymium speaker magnets. Fins around the tweeter perimeter increase surface area also help thermal measure by ambient air.
1-inch Titanium dome tweeter withstands corrosion with a high strength-to-density ratio. The beautiful impermeable Polypropylene cone was designed rugged and weather resistant.
