craig, how do you like the 2 sb2000 you have?? any reason you went with those instead of ported ones? do they play nice with your other 2 cylindar subs>?
One reason - so I could hide them behind the velvet curtains in the front of the room. They just fit. I recently checked whether the SB3000's would fit. Nope - too deep. I don't have room for anything larger, but with the twin PC12 Plus subs in the rear, it's just perfect ! The bass isn't boomy, but you can feel it easily during lots of scenes. In Black panther, the final fight scene on the magnetic train tracks makes the room feel like it's vibrating when the train goes by. It's a crowd pleaser in my theater for sure ! .50 caliber machine gun fire in Fury is easily felt too. 4 subs - 2 front, 2 rear, really are an improvement !!
