What Sub brand are you using?

You can check the spider. Normally the first thing to koyak if overdrive.

If hapens exactly the same scenes, and with lower volume too..
Then i would say it might be the source(disk) got proble...

Could be capacitor leakage.

step by step ma. if straightaway from cap ayam to svs then they wont know how to appreciate the price they have paid

There is a dolby encoded test disc that reproduces the frequencies that u need to test to see if there is a problem with ur sub. Its at the AVS forum and is a free download. I will see if I can find the link, else I will pm u and we can see how I can pass u the disc.

Not sure, but I think azbro wants a software that can analyze the DD or DTS core within a MKV file.

Ronald is right. Moreover it will be taxing for avr to produce low freq. My front goes down to 38Hz, center 49Hz and front wide at 48Hz. I set all to small.

Happy reading. 

To test the sub, do you have access to test tones or a test sweep? You can then play the tones to see if any funny sounds come from the sub. I think you might be able to download REW and use it just to output to the sub and listen for funny sounds.

To test if it is the source, go to a friend's house, play the same scene and listen if his sub makes that funny noise. Personally I doubt if it is the source. It is possible the source might have a very strong bass level, and if you turn up the volume it might cause the amp to clip or driver to bottom out. But this is not a fault of the source, more like the other equipment cannot handle the source.

Tomorrow morning you can tell your neighbor that there is another earthquake in Indonesia tonight

re-watch "AVATAR" last night, compared to my last viewing with Marantz SR6003, it a new experience with Onkyo TX-SR808, the LFE are so much better

Have u guys listened to the LFE on Scott Pilgrim vs the World?

The Fight scenes have over the top punch effects..

And there is the scene where scott and evil-ex-boyfriend number 3 have a bass-off with bass guitars...

hahaha... maybe bolehland is plus 10%..

On lighter note, I think my Mordaunt Short Mezzo looks identical to Triangle Quartet. Observe the tweeter design on top & the curve shape of the speaker box based on the same philosophy to minimize resonance.

Who's copying who  ? Wonder how the 2 pits against each other in pure stereo mode.      Care for a shoot-out?
Htkaki must have lots of comments on above statement.....hahaha. Don't flame me.

azbro,

I'm not htkaki butif the floorstander is capable till 50Hz, then cut it off at 70Hz. (20Hz above the rating). Still set it small.

My speakers are rated at 37Hz. If u look at the anechoic chamber FR u will notice that it is flat till about 60Hz then it starts to roll off. The roll off continues till about 37Hz where it is -3dB. As you can see, it starts to roll off at about 20Hz from its rating. For music, it will do fine playing full range as most instruments (even bass guitars) don't go much below 30Hz and normally not at high SPLs anyway (unless bass heavy tracks).

Also most front speakers are ported and tuned at higher frequencies. What I find now is that a proper sealed sub can supplement a good floorstander for music as well. It just gives u the extra depth... (the warmth that people talk about)

For movies, the fronts and the centre do a lot of work. So to take the load off, setting to small and redirecting bass to a capable sub will allow more definations for the fronts.

There is almost always more bass on a floorstander than a book shelf. (Note  : almost always, depends on the design)

For music, moving from bookshelves to floorstanders were a revelation for me at least.

Just found out that maja_5365 no longer with us . He passed away peacefully on 4th Feb 2011.
