Yes.  I put a set into my T2.  They were brand new (full kit) purchased by a local for an upgrade for his machine, but he finished up selling it and sold them on Ebay at a fairly good price.

It made quite a difference to the sound on T2 - much more base and better sound.  I think you need the right game to put them in.  HS2 - yep, would drop one it, if I had a GNR - for sure.

But its a bit of coin to import on its own.
