Default Best damping stuff for fullrange

Hi,

I own two pairs of fullrange driver:
Alpair 10.3 in Pencil
Betsy K in Baronet

I'm wondering which damping stuff will be better and if there better one for BLH and Pencil desgn.

Thanks in advance Guys ..

Naca

Price/performance, probably something like Dacron 35mm.... "Camper van insulation".

Camper VAN Insulation 1M X 0 7M X 35mm Thick Light Weight Dacron Polyester | eBay

Recycled wool felt underlay (in the UK Envirolay/Envirofelt) is what I stick to the walls around the drivers.

Naca,

For the Pensil 10.3 loose Dacron hollow-fibre polyfill is recommended. The poly-fill needs to be teased out and distributed throughout the cabinet.

If you want to, you can also put a thin layer of felt on the inside side walls close to the driver and inside the top the cabinet. But this is in addition to the poly-fill.

The amount of poyfill you need will depend on you room, amp etc. Start with less and add more as required.
