Makes little difference - the sound waves produced by the speaker will
still go through the floor.

If I have understood the question correctly...

It'll make a fair bit of difference. Solids are rather better conductors of
acoustic energy than air is. So if the speakers are mechanically coupled to
the floor a lot more acoustic energy will be transferred to it that if the
only coupling is via the air inside the room.

** ABSOLUTE ******** !!

** Shame how the damn cabinet is NOT the source of the sound pressure in
the room.

That pressure, distributed all over the floor area IS the cause of floor
vibrations.

So if the speakers are mechanically coupled to the floor

You could try either isolation mountings of the kind sold for various
engineering purposes, or a half-inflated inner tube. I've used both
methods
for optical tables to cut down vibration transfer levels.


** Funny how people isolate their TTs from floor vibrations to stop LF
feedback while usually leaving their speakers alone.

Could be because nothing you do with them makes much difference.

Funny that.......

My Infinity kappa 600 speakers are well isolated by double tiles of 25kg
each, so 50kg per speaker and between the tiles are very simple tabs wich
are normaly used for furniture to preserve scratches on the floor.

You can't do much about it. Using stands will do no good. If it is bass
that can be heard
you just need to turn it down. It is the sound that can be heard and not
from the actual
case itself.

This is not easy; if you make an isolation system that works down to an
adequately low frequency, it is likely that the speakers will be
unstable and wobbly. You could always hang them from the ceiling. Anyone
living above?


** That is 100% IDIOT advice.

The cabinets are NOT responsible for shaking the floor.

Well, you answer the question then - do you need me to repeat it?

How did you work out or measure the LF turnover point of the above as an
isolation filter, and what value did you get? :-)

Particulary curious to know the spring and loss coefficients of the 'tabs',
and the effective mass/ compliance the floor presents to the things above
it.

Slainte,

Jim
