Tune up your touring bike

Rockford Fosgate designed their TMS57 speakers to replace existing 5″x7″ speakers in factory equipped Harley-Davidson BOOM!™ Audio Stage-I and Stage-II bag lids. These rugged, weather-resistant coaxial speakers pack a lot of sonic punch in their compact frames, and factory Harley-Davidson connectors make installation easy.

More cone for more sound

These speakers feature a compact motor structure that drives a reinforced polypropylene cone for outstanding performance in the midrange and low frequencies. Rockford’s VAST (Vertical Attach Surround Technique) surrounds give the speakers 25% more cone area without compromising ease of installation. The 1″ film tweeter delivers clear, crisp highs at highway speeds, and it’s protected from the elements.

The result of all this is that you’ll get more performance from a smaller speaker, which is pretty much ideal for a motorcycle. The element-ready design protects these speakers from wind and weather, while the glass-reinforced polymer frame can stand up to rough roads or sizzling sunlight.
