About The Product
The TMS57 full range coaxial speaker is designed to replace existing 5″x7″ 2-way coaxial speakers in factory equipped Harley-Davidson® “Boom!™ Audio” and “Boom!™ Audio Stage-I” bag lids. The TMS57 features a Neodymium motor structure driving a reinforced polypropylene cone with Santoprene surround. Highs are produced by an ultra-efficient 25mm dome tweeter with integrated phase plug and is made water/weather resistant with the addition of a Santoprene front isolation spider connecting between the tweeter housing and cone assembly. The speaker features two types of connectors, a standard set of terminals for 2013 and older generation motorcycles, and a new Deutsch style connector for 2014 and newer.
