That they closed is sad and a loss to the audio world, but it does not diminish the value of what they have achieved and created.

Speakers can generally go on for a couple of decade before needing to re-foaming or other issues, provided you take good care of them. I am not worried about my ProAcs, even if Mr. Tyler is not around. Just because the company is not around, does not mean the speakers will become lazy and stop making the good music that the owner has come to love.
But, we are not in OP's shoes. So good luck to OP in whatever he chooses to do.
