Strange sound from SP2500 bass.

[xenrayz]

I got my SP2500 a few months ago.

 

At first there were no problems what so ever that I could notice.

But a few weeks ago I noticed that when I turned up the bass some, it made a sound that I can best describe as a part inside would be lose (Kinda like when you hold a paper infront of the airflow outlet.)

The sound increase if I tried to put my hand infront of the air outlet

 

My uncle suggested that it might be some of the isolating that have came lose and caused this sound.

 

Lately I have not really noticed the sound at all, but I restrained myself from playing higher volume music both for my own health but aswell that i got abit worried with this.

 

I tested it today and the noise is still there.

(Once again special noticeable if I hold my hand ifront of the air outlet.)

 

Maybe some one had a similar experience?

Would you suggest me to make a RMA regarding it?

 

Thanks in advance!
