my mission m35s sound very good but with some of the deepest and/or loudest basslines i can hear a horrible rattling noise coming from the bass port round the back of the speakers. at 9:00 and above on the volume controll is about were these noises usualy start.
this is not the problem, all the speakers seem fine the strange thing is that the noise comes from both left and right speakers. In my experience if a woofer goes wrong in any way it will just not make any noise or as you said scrape and sound horrible and also i only bought these about 10 days ago brand new so maybe i should just demand a new pair.?
Yes, I would call the shop and advise them of the problem and if they can't solve it then you should get a diiferent pair.
