Can't possibly go wrong with Proac stand mounts. Year after year, rave after rave from owners.
It's the kind of standmount that even were you to move in a huge theatre, you would not want to part with your proacs.
They do need current, not the most sensitive. And you already have a sub. I think you'd be stunned by how great they sound. I sure was. Talk about "musicians in the room with you!" they have it in spades...
