I have a pair of LS400's and I noticed that one of my tweeters is "blue".

Here is the blue one ... 138_3861_2.jpg

Here is the "normal" one....

Is this bad? I don't notice any popping, hissing or tone deficit.

Thanks in advance.

    What's an LS400?

    That was my thought. The LS series as I know it is the 50, 70, and 90 mains and the CS350LS center

    Could it be a RT400.....

    Not with a tri-lam, the RT400 had a 1" black silk dome. (didn't you just get a single the other day, or was that someone else?)

    It LOOKS like a first gen LS series trilam, but the 400 is throwing me.

    CS400 maybe, and he has two of them??
    Scratch that I see a driver below the tweeter in the second picture

    No Idea
    Dodd - Battery Preamp
    Monarchy Audio SE100 Delux - mono power amps
    Sony DVP-NS999ES - SACD player
    ADS 1230 - Polk SDA 2B
    DIY Stereo Subwoofer towers w/(4) 12 drivers each
    Crown K1 - Subwoofer amp
    Outlaw ICBM - crossover
    Beringher BFD - sub eq

    Where is the remote? Where is the $%#$% remote!

    Just looked at my LS50's and my 350 and they look exactly like those (except not blue)

    That was me...I know where a new one is that I CAN buy cheap....I am trying to find another before I bought it. I did not look that closely at the tweeter but it is a Polymer dome and yes...it is black....my mistake. See... I guess I was hoping that they were the RT400s and I could convince the guy one was shot because it was discolored and he would sell them to me....

    Thats the special one in a million tweeter. Return it to polk and they will give you in return a complete SRT system.:eek: It is kinda cool looking.

    Look at the outer brown-ish rim of the tweeter and compare it to the other bright silver one. Yep... this is a cooked tweeter. My guess - clipping. The coil got so hot that it started to melt the coating. You were VERY CLOSE to bringing this tweeter to non-functional.

    If it's still under warranty, you should be able to get a new one. Polks pretty good about that.
