fulminis, think of the problem in its basic form. What is a broadband absorber? It is a velocity sensitive absorber. What does that mean? It means the absorption of sound energy is due to resistance to gas flow through a porus...

I vote for sealed... you're trying to balance the room (smooth response) not going for Max spl. Sealed will have lower extension and plenty of output at the levels required for the task. Either use the two velodyne subs you have and...
