Tweeter Protection Information

You know what, now that i think about it, ive seen quite a few crossovers that actually have bulbs like that installed in the board on the tweeter output, i dont have an issue with blowing tweeters myself, but this does seem like a good idea, i was just worried about the heat.

Sure, the Polk Audio SR series components are one inparticular.... The heat could possibly be a problem if you ran it so hard they were lit all the time but so far for me we run the volume around 90-95% every time the kids aren't along and hardly ever even see them flash...

It's been awhile since I've bumped this thing.... so...

BUMP

I don't think they do the same thing as a resistor, I couldn't hear any audible difference with them installed plus they will sacrifice themselves for the tweeter.... they really don't light up very often, unless its REALLY cranked to the moon, and even then they just flash so worrying about them being uncovered hasn't been an issue yet in 2 years....

Also a resistor won't blow when it is needed and it will just limit the juice completely. He wants to limit the juice but if he accidentally goes over the limit they will pop. Makes sense really.

Although I would use a fuse instead.

this is a band aid to obvious problems like wrongly set x/o's and gains on amp and possibly hu. although i might be worried what its doing to the freq. range of the tweet.

i remember my dad had some old jbl speakers that when they got loud close to the power limit, the light bulb inside would start glowing to the music haha.

Most high end comp sets do have a bulb in the crossovers, some do not. it's really a smart and cheap way to protect your tweeters.

Kicker has been using bulbs in their tweeter and midrange passive crossovers for years.
