Just got this wedge and I'm doing some programming with it. Really very impressed with it, but I'm noticing a rattle occasionally on low frequency notes. For example, letting a low note ring out to feedback, the rattle sounds like something is loose in the speaker. The speaker was purchased through Mike at Audiopyle, awesome guy, awesome service, awesome price too! When I talked to him, he suggested running playback tracks through the wedge. I did this with mp3's off iTunes as well as recorded tracks of my band. Can't duplicate the rattle with program material. Is it something I'm doing wrong with the Axe? Also, are you guys running it with the XLR output 1 of Axe and the Mic setting on RCF or Output 2 using the Line input on RCF?
Any advice would be appreciated, thanks!
