If it's confined to a speed band, it's likely something loose that's fluttering sympathetically with a vibrational frequency occurring at that speed. It'll take some checking around to figure out what could be loose.

Try running with the AC off. It could be wheel balance.

The plastic lining has broken loose under the car and is either hitting the tire or the ground and flapping as you get high speeds.
