...from folks that have taken their LSiC apart

I am the original owner of an LSiC purchased from an authorized dealer 11/26/11(black Friday splurge). Sounded good when I got it, but have been liking it less. I figured it was because I modded the XO of the LSi9s it was paired with. I put it back with some stock LSi9s, but still seemed off. So, I purchased some caps, resistors, and figured I would mod when I got the time. Saw an LSiC pop up in the FM so I grabbed it to use while I did my work.
Here's where the help is needed. My original has always been behind a screen and on brick. When I tilted my original slightly to pick it up to test the used on from the FM, it felt an sounded like a large book slid across the bottom of the cabinet. IF you tilt the speaker slightly from left to right or gently shake from side to side, you can hear something sliding and feel something shifting. And the used one sounds better.
I guess I should wait to call customer service on Monday, but I am not all that patient. Any idea what this could be shifting inside an lsic? or the best way to open it to find out?

Perhaps a magnet from one of the woofers?

I am curious as to what it is. Please let us know.HT: LSI15, LSIC, LSIFX, Emo XPA-3:biggrin: Onkyo TXNR809, Sony BDP-S500, PannyDMP-BDT320, MIT S1 SC. Mit 73842dlp

I think I will wait for customer service call on this one. I took the grill cloth off and the tweeter "dust cover" area looked distorted or unusual compared to my other lsi sets. It is loose and not connected to anything and the "sound" of the rattle is coming from the center of the box... It's a center so I haven't pushed it loud and it looks visually wrong. I guess time to start the wait...

Well, I guess I should have started my thread in troubleshooting.
If this had been an RDO198 from my RTA15TL I might have a clue as to what happened. A limited use center channel has me baffled.
I could not wait so I pulled the tweeter due to how bad it looked from the outside. A bad tweeter would also match why I did not like the performance of the speaker. The magnet rolling in the cabinet is what I heard rattling around. It got so hot, it melted itself through the screw mounts and fell off the back. Look at the back of the faceplate. A quick glance at the XO board did not indicate any hot spots. -
Well, I guess its back on the phone tomorrow. Can you spot the problem? "the voice" came on tonight...which I don't watch...and the pitch was horrible...and the judges just kept raving...so I DVR rewound...and still HORRIBLE... I thought what the heck...and found this... Guess that explains part of the problem. I used my other LSiC while this one was out and it is still fine, but now I am almost worried to put it back in service?

What were you powering it with?
-
Onkyo TX-NR5007. I know AVR is not ideal...but its no slouch in the amp section and I was not crazy with the volume knob.

If I had to hazard a guess, I would say faulty crossover...
I mean, it has happened twice on the same speaker while another LSiC has worked fine in its place with no issues.
And the tweeter has been replaced...definitely points to a crossover short or faulty cap/resistor in that particular speaker."Some people find it easier to be conceited rather than correct."
