PROAC RESPONCE 2 replacement drivers ???

Unobtainium. Great little speaker btw.
They were made specially for Proac by SEAS, without knowing the T/S parameters, you’ll never find a sub. You can get the roll surround done if they are still working if that’s all they need.

I owned a pair and georgehifi is correct. I had the surrounds replaced. Usually that is the only thing that would go wrong with them.
