[QUOTE="JimGore, post: 73538, member: 3"] Hi, Use about 3 lit for the displacement. If you are a couple of lit out on the final internal volume it won't be too much of a problem. You saw that the 50% increase in volume only caused a 2.5Hz shift in F3 in the earlier scenarios I did for you. As long as you are within about 5lit of the 120lit you should be fine. I realize we haven't discussed damping material anywhere. Keep in mind you will want to add some form of damping material to the internal surfaces of your enclosure before the driver goes in. I usually use those cheap "dog blankets" you get from hardware stores, cut it up, and staple it in. Cover at least 80% of your internal surfaces with it if you can. Regards, Ian. [/QUOTE]
