The TMS69 full range coaxial speaker is designed for use in bag lid applications for motorcycles. Designed lightweight so it doesn't weigh down your bag-lid, it features a very powerful Neodymium motor structure for a fraction of the size and weight of traditional ceramic ferrite magnets. The driver uses a co-molded, reinforced polypropylene cone with Santoprene surround. It also features 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.
