[QUOTE="Beat_Dominator, post: 2692886, member: 560107"] Generally, if the room is smaller than a large high school class room, and you use a long-throw (xmax > 16mm) driver 12" or bigger, sealed with ample power would realistically be enough for most people in a system used more for movies than music. (JLs HT subs with the W7 drivers are all sealed I believe. If you want to have a more flexible sub, ported low around 27hz, with proper eq, will be able to fit in a huge variety of room sizes and fit musical as well as cinema needs. The real issue is size, and if you want to tune realy low, you need long ports, add that to the 1.5-3.0 cubic feet of volume in the box you'd need for a lot of 12s and you end up with boxes bigger than a mini fridge pretty easily. You can always tune higher in the mid 30s and still get faveorable output though, so that might be an option for you. [/QUOTE]
