Hi again.
Zilchermania Dyer !!! I have a real interresting DYE project for you …
In regards of complexe modulus and damping factor; I offer small experiences for you.
(anothers yuk yuk yuk )
If you agree:
Peel off completely the damping stuff on one horn.
Build a wood box (any mdf or same is ok)) where the motor is out of the box but all horn is inside.
Yes oh yes. Fill the entire box with sand!
And finally put 2 hard feets on front floor box and one in centre back.
Keeps measure of each impulse test is the best way in this aspect....
and compare audio test response by your ear (especially play cymbal or any instrumental piece with rich harmonically in hi-frq.)
More???
Fill box with silice white sand in box… difference (filter pool sand)???
More ???
Add a maximum sand silice to paris plaster and fill the box….
(The plaster is easy remove)
Post your comment.
this is 3 excellent way of the structural damping for low money with out hi-tech instrumentation.
