Where can the bitumised felt wall damping be found, if not what are substitutes?
In Europe it is commonly found in building supply centres, USA (roofing felt) at some Home Depots, and in Australasia it appears difficult. Substitutes may include other speaker damping products such as Blackhole, lead or barium impregnated rubber or vinyl sheeting found at car repair suppliers, rubber shops and DIY audio/electronics centres. Commercial floor vinyl has also been suggested and acoustic engineering suppliers have various products such as Deci-damp vinyl sheeting. Sticky-back, bitumised and lead lined car panel damping sheets are highly recommended and cost effective. The objective is to use a mass loaded material to absorb vibration, providing about 4kg/9lb additional weight to each speaker cabinet.
