It's nice to see that this forum is up and running again.
One of my 612's has a slight distortion and when I turn it up I can faintly hear a clicking (possibly a rattle) sound. I used my other 612 speaker to do a side by side comparison. From a distance you can't really tell any differences in sound. I then hooked the speaker up to a mackie mixer and killed the highs/mids and left only the lows on the EQ and definitely noticed some distortion when turned up.
Does this sound like a major issue? I thought I would get a second opinion before I decide to send it back to JBL.
Any advice would be greatly appreciated.
