The Acoustic Steel has the extra ordinary ability to absorb energy in the form of resonance. The
absorption rate is clearly demonstrated in the graph below. Noted all results are from an independent source. All tests measure the transfer of vibration from the speaker platform to one of the base spikes, i.e. it
works both ways (vibration from the floor to the speakers or vibration from the speakers to the floor).
The 4 test conditions are:-
 1) no damping or inert filler in column
2) inert filler in column
3) inert filler plus acoustic speaker plate
4) inert filler plus acoustic speaker plate, plus acoustic base plate
As expected, the results show a remarkable reduction in vibration response, which
could otherwise "colour" the sound produced. The Y axis is in decibels with 5dB steps. A 10dB change in vibration level is a factor of 3 (i.e. a 10dB reduction means
that the vibration has been reduced to one third) and a 20dB reduction is a factor of 10 (i.e. a 20dB reduction means that the vibration has been reduced by 90%). 30dB = x30: 40dB = x100
The Acoustic top plate reduces the vibration by x100 or more over muchof the frequency range. Adding an
Acoustic base plate reduces the remaining resonance by a further factor of up to x100 (a total of x1000 at some frequencies compared with the inert filler alone).
The Speaker Stands used in the test were the award winning R/S 300 with standard 4mm top and base plates
. Existing customers can purchase Acoustic Top Plates and Acoustic Base Plates as an option extra to enhance the performance of their Stands.
Acoustic Steel Isolation Platforms are also available to enhance the performance of Custom Design Hi-Fi and
AV Support Systems.
