Woofer damage from new Star Wars THX DVD?

I'm currious to know what amp you are driving your Utopias with ?
It appears to me that this is another case, in my experience with HT systems, where THE POWERED SUB SHOULD BE HANDLING THE BASS!
PASSIVE speaker systems, LARGELY should not be handling demanding bass from dd/dts soundtracks! I know far too many people play there "full range" speakers as "large" for movies in a "passive speaker system". And it's never going to have enough control over the bass drivers in a PASSIVE speaker to handle bass properly! I can CLEARLY overdrive the bass woofers on a pair of large Dunlavy SCIV's (4 X 12" woofers)when playing full range on some of the movie mixes out there. And I can do the same on other large speakers. I don't seem to have this kind of challenge driving active woofer designs, like Def Tech BP2000's or Infinity Prelude MTS's!!!
I've said it time and time again...."Unless you're using full range speakers WITH ACTIVE POWERED WOOFERS, you should be configuring your speakers as "small" on your pre/pro, and letting the ACTIVE POWERED sub handle the bass!!
The damping factor and control that's possible through PASSIVE CROSSOVER NETWORKS, isn't sufficient for dynamic transparancy in the bass reigion at the very least. In a powered subwoofer, the AMPLIFIER is RIGHT ON TOP of the bass driver, utilizing "TIGHTFISTED" control over the driver.
There's a reason THX has specified a 80hz setting for it's processing between bass woofer and main speakers...because it works!!!!
I bet what happened here was a case of Amplifier clipping, which cause the woofers to overheat and melt the voice coils! What Did JM Labs Say?
Anyway, my theory...

Ooops!..I meant Dunlavy SCV's, not SCIV's!(when refering to the Dun's being overdriven...sorry.

sounds like you have a similar setup as me.. apart that I have Wilsons. What I did was buy two subs (left and Right) and put the main on a cross-over at 40hz.

I rather blow my subs then main speakers... BTW.. my Subs bottomed out at one point in the movie.. I think it was at that point

I agree with foreverhifi. On video apps I have my subs pick up everything below 80hz. I don't want to overload my mains even though they are quit capable. On two channel or other audio I have the subs pick up below 50hz. This way I don't overload bass on my music and get the complimentary effect with my mains. I am however intrigued by the new stars wars dvd. The helicopter scene in Matrix makes my bones rattle. Can't wait to hear this.

I have played this DVD on both my HT system (Paradigm 100 V2 and VMPS Larger Subwoofer) and on my music system (Mezzo Utopias), both at higher levels than I would ever do normally. The Utopia woofers suffered no damage whatsoever and did not bottom out, though their output was obviously less than the VMPS sub. I can't help but believe that you experienced an amp problem. We tend to think of only tweeters being damaged by clipping but I suppose it could happen to woofers, as well. Sean, does this sound plausible?

I agree that you should raise holy hell with your dealer and with the mfgr about warranty coverage of only one woofer. Absurd!
