DVDboulet, there is very little difference between the 7 and the 9, sonically, they are the same speaker with the difference being a slightly deeper bass response in the 9H
The real advantage the active bass system is in the speakers adaptability.
If you have a larger room and have lattitude where to position the speakers the 7 will be perfect, if the room is smaller then a good sized room lets say 25-30 foot long, 18+ wide etc, the 9H will be ble to produce tight non boomy bass.
So it comes down to room size, and positioning.
If someone has the extra budget the 9H would be better, as the bass will always be good, and if not and the room has size and the ability to position the speakers go with the 7.
Hope that helps.
