So yesterday I traded my retired Rti10's for some Magnepan MMG's. My first impression is that I've never heard stings sound so realistic. They blow the snot out of my Dynaudios for violin, cello, etc. Very impressive realism for this type of music. They aren't as strong for rock music for my ears. They seem to be missing the punch and umph that my Dynos give me. They definetly need the help of a sub. I know that a factor is that the bass is soo tight that I'm not used to hearing such clean bass. So I'll be adjusting to this new sound for awhile.
Here is a problem I need some advice about: at around 40hz, one of the maggies seems to bottom out and distorts. It sounds like a rattle or like something is vibrating. It is very noticeable. The other speaker is fine. I've narrowed down the location of the vibration to be coming from the top back part of the speaker. Any ideas how to correct this?
