811 Fins

[RonSSS]

So, I presume the sand and latex paint will work equally as well on the 511 horns. I understand the 511's ring worst than the 811's. I have not had the ringing condition on my 511's but, I would like to know of a remedy should ringing occur.
Thanks...

Sand and latex about, 7 coats make either dead like wood. I don't care how hard you screw it to the baffle, or cut the middle of the ribs and replace with RTV...they don't come close.
