Almost all systems needs subs unless the mains have active subs.
I would add a watch controller from wilson ($4500). It will take the system to a different level. You could pass higher then too if you are currently coming in under the mains (not as good as passing at 50-60z) imo. The downside is the additional wiring...
JL CR-1 would be a cheaper option.
