    tweeter protection. Polk used these before poly switches. I like fuses more personally, except if a fuse blows you have to replace it. But that also helps you with volume control :-)
    Please. Please contact me a ben62670 @ Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.

    alot of the older polks has fuses in the back to protect the tweeter. it would suck to have to replace the tweeter every time wouldn't it? a $2 fuse is much easier on the old pocket book huh? ;)

    The new SR component speakers use these bulbs in their crossovers for tweeter protection. This way, the fuse will blow before the tweeter. Works like a charm - when setting the gains, if the bulb lights up you know youre pushing it pretty hard.
