Im soon to be in a new dedicated theater and I want the bass to felt and to hit nice and deep. I currently run a PB 12 Plus 2 in a smaller room and it does an exceptional job and then some. The new room will be 20x20 with ceilings at 8 feet. I definitely want to add a second sub to sort of balance everything out. I was wondering if I should go with the JL Audio Fathom 113 or should I just add a 2nd PB 12 Plus 2. I've been reading rave reviews over the new JL Audio, has anyone compare the two? The rest of the system consists 126 inch Carada, JVC HD1 front PJ, Polk Audio RTi12s, CSi5, Rti4s, FXi3s. Pre/Pro is Sony 7100ES, and speakers are driven by Outlaw M2200 mono amps. Any advise would prove helpful.
