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.
