    Default Speaker ID, Blown Tweeter

    I have set of older Polk speakers that I think I blew the tweeters in. I jumped the fuse on the back of the speakers (bad idea. I know) and turned them up pretty decent. Now the tweeters have a constant hissing sound coming from them that gets louder as I turn the volume up. I seem to also be getting occasional distortion. It is hard to tell though because the acoustics in my dorm room are about as bad as possible. Does this sound like a blown tweeter to you?

    Assuming it is a blown tweeter, can anyone help me figure out what model these speakers are? The serial numbers start with 5B. Is that monitor 5B? All I can find in Polk's vintage speaker listing is the monitor 5, which does not seem like my speaker. I would like to ID these things so that I can order replacement parts.

    Lastly, what kind of fuse should I run on the back of these things to avoid a repeat performance. It just says "small fuse" or something on the back. Thanks for any help you can give.

    Yep, Monitor 5B's. Pull the tweeter out, on the back is a label, it will tell you what tweeter you have. I'm not sure what the fuse value is, but you can ask Polk Customer Service when you order the new tweeters.

    Oh yeah, turn it down.

    Yes, more than likely you pushed your amp too hard. 'Clipping' is your word for the day.

    Thank you. I am on a mission to learn all about clipping. From what I can find the tweeters seem to be SL1000's. So I can replace these with SL1000's or SL2000's. Is that correct?

    Polk no longer sells the SL1000 or SL2000, so you'll have to hunt the FM or eBay if you want the exact same tweeters or you can buy the new silk replacement tweeters from Polk.

    Thanks for the link. I am reading through it.

    I talked to Polk earlier today and they said they could sell me new ones for $60 each. Are they probably talking about the silk ones then? I am pretty sure they said that they were SL2000's and that they were sonically identical to my SL1000's. Sorry for all the questions, I just want to be sure I choose the right replacements. Thanks.

    What you want is the RDO194-1, which is the replacement tweeter for the SL1000/SL2000.
