    At the risk of sounding obvious - I assume you were playing it pretty loud. (or at least beyond the capabilities of your amp)

    To put it in another analogy - If you get a new car, over rev the engine and it blows - is that your fault or the manufacturers?

    Call polk customer service and they will take care of you. Do not for a second think that the problem was with the speakers though. You need a more powerful reciever, a good amp, or more efficient speakers if you want to play at high volumes (high being -10 or lower on a calibrated system) perhaps a combination of those three suggestions would be in order.

    Good luck - stick around and learn what went wrong and how to prevent it in the future.

    Yeah, I agree with above comments...

    What model speakers do you have and what gear are you driving them with?

    Not having experience with those speakers, i probably won't be able to help arrive at a concrete conclusion. BUT: I can honestly say that i've never run a reciever even that high, and being that it's not particularly high-powered, i wouldn't be all that surprised to find that distortion killed it.

    But again, there's way more to it that could affect it. Just a possibility that my brain jumped to.

    What were you listening to?

    Wow - I agree, at -18 (assuming you either calibrated by hand or ran the YAPO on your yamaha) you should have been good to go. Looks like we will need some more info. I assume it was not a gradual thing.... What were you playing (what movie) and where was it at (what scene - if you noticed anyway).

    How is everything hooked up (DVD to reciever to speakers) what kind of cables - for the speaker wire - what kind of ends are on them....)

    There is something off here, we just need to find it.

    welcome to Club Polk.

    If it is only a single tweeter then that is an easy fix.....

    will your authorized Dealer take care of the issue ?
    anyway
    ...things happen and LUCKY for you that POLK AUDIO customer service
    will take care of your issue especially since it is new.

    take the time to figure out what the true root cause of the failure possibly was.
    clipping
    a sudden pulse or noise.
    distortion.

    good luck and welcome again to club polk.

    The horn in war of the worlds (after the first pod emerges) has blown many center channels. not sure why - but it does. (can search on AVS and even here for some other centers that bit the dust on that one) but still -18 should have been fine. (much below -15 and I would be blaming the volume though for that movie)

    Anyway - do you happen to know what level the center is set at in your AVR? The pre-amp channel can clip and blow a tweeter just like the standard amplifier channel can. The big difference is, the pre-amp channel can do it at lower volumes. (but it is also more rare)

    I assume you are not bi-amping / bi-wiring or anything like that??

    yes all speakers set to small, crossover set at 80hz. i hope i just had a defective cc and will have no trouble with new one or front l/r. now i just need some surrounds to replace my broken paradigms, literly broken.

    even though a tweeter or other driver blows from use or mis use.. I"m not sure which is the case here... Polk Audio carries replacement parts. call customer service and let them know the model of your speaker.. AND mention to them you are a Club Polk member for a discount on part(s)

    *also, on rare occasions speakers have problems and a part dies for no apparent reason as well. So some times even though you are not over driving them... a problem could still arise.

    good luck and call Polk customer service... they will help you out. :D

    from my experience with the Yamaha product line, I have little doubt that the amp section simply cannot keep up with the demands placed upon it by the speakers even at the level the OP had his system set to... I found this out in my own rig with a much beefier receiver and went Sunfir instead for power...

    Maybe with the lower end products, but the higher end Yamaha's would have no problem driving speakers at -18.

    I ran my 5.1 from my V1800 no problem to higher levels before using my external Carver for the mains. It still drives the center and rears and I've gone up to -4 for some music and movies...clean and clear.

    Well glad you got your issue resolved. Of course we can't rule out a manufacturer defect- that is after all what a warranty is for ;).

    Now what the heck is that speaker? And what is that thread thing hanging behind it?

    :D:p. No I didn't mean through Abby, I mean through the magical software they use. You know where they can take a super low res pic from a MAC Machine (or whatever the heck they are called now) and ultra zoom in on a car a mile away and use the computer's advanced algorithms to dither the image to a super clear and sharp hires image enough to discern the reflection of the attacker and extract a DNA sample from that image???? Of course it could be Abby operating that computer...:D:cool:
