And here was I thinking that for a speaker to work correctly (i.e. as designed) and at optimal efficiency, the cabinet had to be 100% rock solid.
-i.e. NO MOVEMENT WHATSOEVER !
Any movement in the cabinet results in degraded sound.
I’m with @erik_squires on this one
One experiment a friend tried that supports this...
- he has monitors on a stand that rests on carpet.
- So we tried placing 15lb weights on top of the monitors
- the sound improved greatly - i.e. once the cabinets stopped being moved by the drivers
Adding heavy weight to the top of a speaker is a very affordable way to improve things, but it gets expensive if you want to make it "pretty" :-)
