When combined with Inert Acoustic steel Top plates and CR4 Steel Base plates the reduction in resonance noise vibration is significant, resulting in an improved performance and sound quality. Please visit our Acoustic Steel page to view the graph demonstrating which frequencies of resonance vibration noise are absorbed by each process and the combination of Acoustic Steel top and base plates with our specially selected Inert Filler material.
Custom Design sources all cardboard packaging from only PEFC or FSC certified companies. 76% of the cardboard packaging has been manufactured from recycled material which can be 100% recycled.
Rigidity is proven integral design feature which improves sound performance. The Custom Design philosophy of multi column supports provides superior sound quality and performance over traditional single column support design speaker stands.
Custom Design do not use Aluminium in the construction of any speaker stand designs. The natural properties of aluminium prevent speaker stands from performing to the best of their ability as mechanical feedback can be prevented, just like over mass loading. Which will result in reducing the dynamic range and the depth of bass frequency.
