Shaker 6” x 9” Speaker System for Sale. These 4-way speakers deliver serious punch and clarity. They have a massive neodymium magnet and a symmetrical voice coil that can handle up to 650 watts of power. A woofer cone made of mica-reinforced polypropylene means awesome rigidity, low-frequency responsiveness, and weather-resistance. Shaker adds a midrange cone so you get the most out of chunky guitar riffs, powerful drums, and distinct bass lines that otherwise would remain hidden when listening on sub-par speakers. The two dome tweeters add in all the high-frequency details that make music exciting. Used, but in great condition. C/w metal grilles for custom installation.
