Smooth and clear If you're experiencing a muddy soundstage across your dash, it may be time to change out your vehicle's worn-out factory tweeters. Infinity's REF757T 3/4" dome tweeters will bring refreshingly warm detail to your music and provide an improved stereo image — without being shrill or causing harshness. This side view of the tweeter shows one of the installation option that Infinity provides. Bring on the power Infinity uses an edge-driven tweeter design and a large voice coil to help this tweeter handle up to 45 watts RMS. The package includes in-line crossovers that protect the tweeters against lower frequencies, along with adapters that allow for surface- or flush-mounting, so that installation's a lot simpler. You can use the included Starfish mounts to place the tweeters in many existing tweeter openings.
