How about using some Black Hole? It's pretty thick, so you may not have to use it on all surfaces, and it's very beneficial in controlling resonance anyway.
Best way to decrease the internal volume of a sealed speaker?
I have a very fine sealed 0.75 cu foot cabinet that I would like to reduce the internal volume to about to about 0.45-0.65 cu feet. There is limited space to add things like bricks, pavers etc inside.
I am thinking of using some plastic containers with lids glued to the inside cabinet. Should they be filled with sand?

roxy54, Thanks. but what is Black Hole? Is it a spray? bdp24, Thanks but how will the bracing be attached? The internals of this cabinet is pretty tight. See link below. https://www.parts-express.com/dayton-audio-mtmc-075bk-075-cu-ft-mtm-curved-speaker-cabinet-gloss-bla... ozzy |
ozzy, Black Hole 5 is a 1-3/8" thick cabinet damping pad with adhesive on one side. You attach it to the cabinet's interior walls to damp panel resonance and absorb internal reflections. GR Research sells an even better panel damping material named NoRez. Bracing dowels can be secured to interior cabinet walls with wood glue or epoxy. |
Cascade V bloc..Thick purple paint..sucked into the mdf..seals the contents of the wall material from the energy robbing glue and saw dust that kills the dynamics. This product drys hard like concrete.. You could add a quart of micro bearing steel to increase the amount of base solid content. Dont use sand, kitty litter, rice, or lead..Tom |
