Clabe,
I know of a couple Raven One owners using copper mats and centre weights.
I asked Jeffery Catalno the sole importer and dealer of TW Acustics here in North America about using a centre weight.
Jeff does not recommend using a centre weight so I never pursued it.
This was prior to a copper mat available, can't say if it would also colour the sound. Best to ask Thomas or Jeffery before you buy.
