The mystery was solved! I totally forgot the K2 took a 'header' off the table when some yutz was grabbing some feed line and the radio landed on it's back during field day. When I took the radio apart today I could see the speaker didn't look right. I installed an elecraft replacement speaker and it sounds as good as new, thanks guys!
