My ep 500 is making noises still - 01/12/08 08:57 PM
Well, I put in the replacement amp from axiom. When I shook the old amp after removing it I heard a faint metallic rattle.
I put in the new amp and I think that this light metallic sounding rattle is gone, so all was not lost.
However, I hear a vibration noise comming from my sub still. During the test tones with the sub playing at 75 db from my listening position everything is fine. When I turn the volume up at the test tone screen fairly loud the noise starts. I will have to check again but I think the noise starts when the sub gets to about 85 db from my couch which is about 13 feet away.
The noise is no problem during most LFE scenes. Sometimes during movies of course there are extremely demanding scenes... Like on finding Nemo when the little girl is tapping on the glass.
I recorded this scene with my camera so you can hear the noise. I unplugged everything except the sub during the scene. It sounds a little different then this in person but you should get the idea.
I have the gain on my sub at 7 oclock on the sub and it is set to -10 db. This creates about a 76db sound when all my other speakers are playing about 75 db, so it should be calibrated properly.
I turned the main volume up after the 1st or second time playing the scene so you can hear it better.
During this movie I think my sub was playing at close to 90 db when sitting on my couch. This seems like a normal peak when watching movies at slightly above average levels....

Is this just 'normal' enclosure vibration from the ep500? My sub is calibrated properly with my system, but there are still high peaks of lfe during movies which cause this noise to show up
