I'm saying three Pi subs are well-suited to mate with two Pi speakers. But other subs will work well too.
If you already have subs, what exactly are you looking for? You said you wanted "punch," which I think usually means midbass impact.
I think what you might be looking for woud be best served with an upgrade to four Pi mains. They give more powerful midbass, and are more powerful and accurate overall.
