** Bet your floor is vibrating in sympathy with SPL at low frequencies.

Then the speaker stand vibrates - cos it is supported by it.

Then, the un-secured box drifts forward.


It is a suspended timber floor.


** QED - end of story.



I thought it was more to do with air being pushed out of the rear reflex
port and hence proximity to a wall.


** Err - the air goes in and out, same air, over and over.


I don't know if it makes any difference to sound (I've never done an A-B),
but the fact remains the speakers move about if I don't 'tack them down,
and they'd eventually fall off the stands.


** That must be very funny.


Woof , woof, woof, woof ........ thump !!
