2 Pi tower questions


What is this speaker ohm ? 4 ;8; or 16 ohm
I am burning it in and overall it is sounding very good and very efficient
Cabinet is not glued up yet, it sits 9 feet from room corners and 7 feet apart with almost no toe in. listening position is about 8 feet. I am using twin sub crossed overed at around 75 hz
Since the tower was supposed to be able to go down to 30hz - I was surprised to see that I needed at least a sub at 70hz to get the fullness of the spectrum I like in the room
Any comments appreciated
Thanks
