outlaw or infinity

I need to purchase a new sub, I am considering either a lfm-2 or a infinity ps10 or ps12. My space is approx 15 x 24. I hope to eventually be using 2 subs ran by the 990/7500combo. My current other speakers consist of 4 jbl s38's and an s center.
thanks

Not a big fan of Infinity so obviously in this case I'd say Outlaw for sure.
