Re: [LAU] How to reduce bass in the building

Hi Philipp,

Have made this here and it's ok for my ears (and neighbors don't
complain !) :

Top of the shelves are just upon the head when sit.
Distance between speakers "center source of sound" are the same than
distance between nose and each speaker.
Between the wall and the support of the shelf : rubber slices (some kind
of 4mm "plumbing joint") crossed by bolts.
Between the support and the shelf : rubber slices again (call that the
cheap "silent-block bolt"))).
To angle the speakers : a 5cm wood cube, so the speaker rest on its
front edge and on the wood edge (less contact surface = less vibration
IIRC).
PLUS, you can add somme rubber under the edge of speaker and wood, in my
case not necessary.

Of course, if your kids, cats, dogs, or drunk friends are supposed to
jump around the room you put the speakers in, I will not recommend to
have speakers in that kind of position 60cm above your keyboard and
audio gear... without addind a "security chain" (big steel cable with
some plastic around) between the speakers and the wall (have done that,
using 1 "bolt nut" of the speakers' back). In other situations, if you
don't exaggerate the angle (means calculate the size of the wood cube)
it will probably be ok.

HTH, some words are between " " because not sure of translation !
