Question

While listening to music a little louder I witnessed a rattling noise in my speakers (especially in the left speaker) when bass notes played, so I proceeded to double check with Youtube bass testers and found out that the rattling sound was present from around 120hz to 55hz.

I do not think this is supposed to be like this so I will send them back, but I wanted to know if it is a normal thing with these speakers and if any other eris e4.5 owners had the same problem.

Answer 1

Either the spider has loosened up or there is warping of the cone near either the edge/near the center pole and voice coil.
It's not a manufacture specific issue, there a number of factors that could cause this. Have them checked by the seller under warranty.

Answer 2

I had this same problem with my Eris. I took to my local handyman that fixes washing machine, tvs and stuff like that. He fixed the problem and told me that it was a blown capacitor that needed to be replaced (motherboard was overheating as a result). Hope this helps.
