That was to treat the acoustics of the room and will have little effect
on sound transmission in/out of it, especially at LF. For that you need
mass - lots of it.

Righto. The building looks very much like a CLASP style of construction, so
I suspect the best bet will be to give the neighbours my number and ask them
to ring me if it's annoying them. Having been present for the demolition of
CLASP buildings, I don't have much hope of listening to music at a decent
volume.

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.

It occurs to me that a few layers of bubble-wrap might also do the job if
the speakers aren't too heavy.

However you may find that there is still noise downstairs. And anything
that really isolates may also be unstable, so try these methods with care.

Slainte,

** 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.

Are they of particular historical interest?

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,

So they may have either decided it would be a waste of time to go on
objecting, or your music is so loud you can't hear them knocking on your
door? :-)

More likely prolonged exposure to his music has made them deaf too.

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.
