The P363BK from Infinity is a 3-way passive floorstanding speaker. The speaker has a low-resonance bass-reflex cabinet that houses a pair of 6.5-inch woofers, a 4-inch midrange driver, and a 0.75-inch tweeter. Each of the drivers uses proprietary Metal Matrix Diaphragm (MMD) technology to deliver accurate audio reproduction with low distortion for natural, lifelike sound. A tweeter waveguide provides a wide sweet spot for excellent on-and-off-axis high frequency response. The drivers are magnetically shielded for safe use near video monitors and other electronics.
