| Buy a large bottle of white (carpenters) glue. Mix it with sand in appropriate proportions to form a thick paste. |
| |
| Apply this paste in coats to the interior of the enclosure. Allow to dry. |
| |
| The glue + sand mixture forms a solid cement-like coat on the surface of the enclosure's interior, making it less prone to resonance. |
| |
| The overall sound will be tighter, solid (the effect is more pronounced on less-expensive, non-braced enclosures). |
| |
| It is a MESSY proposition - but allot of fun. Get surgical gloves to limit the clean-up. |

This
is a very effective treatment on damping enclosures-
I've used it before, using latex paint instead of the
glue. I've found an elastomeric sealer called NP1,
manufactured by Sonneborn that's just like snot- it
sticks to anything. You can texture it by using a stick,
nail or whatever and you can control the thickness. The
only drawback is that it takes days to weeks to cure. It
kills standing waves in its tracks! My last speaker
project was a killer using this stuff. Make sure each
wall has a totally different texture than each other
wall. Remember the 180 degree thing with sound waves?
The back waves get totally scrambled and dissipate
quickly as thermal heat. |

Minor
correction to my above comment- my mistake. 90 degrees,
not 180. |
