Tweeter Mounting Choices:
– The tweeters can be flush mounted using the provided flush mount brackets and rings.
– Once installed, the tweeters offer a swivel capability of approximately 20° to enhance imaging.
– Alternatively, you can mount the tweeters in factory tweeter locations, concealed behind factory tweeter grilles, utilizing the stealth mounting brackets supplied. (Note that the stealth brackets have multiple tabs for various mounting configurations, and unnecessary tabs can be easily removed.)
– Please refer to the chart below for minimum factory location measurements, keeping in mind that some tabs may need to be removed for a proper fit.

1 review for Alpine S-S65C S-Series 6-1/2″ component speaker system

  1. Josh

    Alpine gives a ton of value with the S-series line of speakers available in co-ax and components. These speakers utilize design elements that trickle down from their R-Series and X-series speakers. For 6.5 component speakers around $150, no one comes close to the value that these speakers bring. Like most components you’ll want to run these speakers off an amp and they will perform as promised. The silk tweeters are smooth and the mid bass is great. Don’t forget to sound deaden to get the most out of your speakers!
