Audix i5 - strange feedback?!

Assuming you aren't doing this directly in front of amplifying speakers, tt sounds like something is resonating. Check to make sure the grill is tight. If it is, take it off and see if anything is obviously loose inside. Mine definitely doesn't have that issue.
 
Goddammit.. This was dumb as fuck! Solved, thanks :D Somehow the Unidyne is much closer than the Audix. Dunno how I came up with this dumb idea, recording in front of my speakers :D
