RCA K130 Speaker

[dsndblm]

Our RCA K130 was one of my first tube restoration projects over 15 years ago. About 5 years ago I had Hank Brazeal recone the K130 speaker, Hank did a great job, the speaker was perfect. A while back I asked my young son to turn the radio on, he did and turned the volume all the way to max. When the 30 watt radio warmed up, it blarred, he freaked out and ran. I got up and turned the volume down, now the speaker buzzes and rattles badly. If I gently push the speaker cone outward the distortion kind of quits. Is my voice coil warped? Are there any adjustments I can try on the speaker?

Thanks
