Thanks

Is the original brown paper product "batting" still inside on the walls and rear panel? If not, it should be replaced. Some folks use R-9 or R-11 insulation material instead, stapled in the same fashion as the original. You can also remove the metal "gliders" on the risers (if you use the riser), and replace them with rubber "feet". That also helps isolate the cabinet from vibrations from the floor, etc.

Corwall users have also been known to apply dampening substances to the metal frames of the woofer and the outside of the horn throat. Its kind of like a modelling clay which sticks to the surface and reduces ringing etc.

Hi,

Yes their is the brown celluluose wadding but I'm thinking maybe trying dynamat?

I am using Herbies Audio Lab Big Black dots and they really work well,but I need to remove those silver domes of silence so that I can place the dots on the cornes for better contact.

Caution: do not use anything over the original thickness or exceed the other dimensions. I would recommend a polyester batting material of about 3/4" in thickness. Do not get carried away. I made this mistake, on the first try, since I had access to dampening materials. I used a high quality convoluted (2" thick) polyester foam. It actually "choked" the bass response. I had to go back to original dimensions with similar material , and the bass returned.
