Have you ever been to space? The easiest way is to start with aerospace technology. This is exactly what has been implemented in the GLADEN AEROSPACE 165.2 active two-way speaker system. The newest technologies, such as the creatively engineered and precisely manufactured basket, seven-layer sandwich woofer cone and the low-resonance dome tweeter, all result in a high-class speaker system that satisfies the highest demands of audiophile enthusiasts and SQ competitors. Aerospace technology just landed in your car but without an astronomical price.
