This is an AL Audio GSK-500 5.25" car audio speaker component system. This component system includes two high quality green injected woofers, two tweeters and two external crossovers combined to create a premium full-range sound reproduction system. Each mid woofer speaker is equipped with a 15oz. magnet and a 1 inch high temperature aluminum voice coil, which allows for extreme power handling capabilities of up to 200 watts (100 Watts RMS). These woofers will deliver strong drums and bass, along with clean reproduction of the midrange frequencies. The two included external 2-way crossovers provide a network of filters designed to deliver specific frequencies to the appropriate components in order to relieve unnecessary strain that can be inflicted in a typical 2-way speaker configuration. Also included, are two 1 inch soft dome tweeters which create high level sonic details that will cut through an entire audio spectrum, filling the vehicle with remarkable sound.
