Does it seem like front end or rear? Speed related includes the driveshaft. The faster the car is moving, the faster it rotates. If the problem isn’t obvious, use a GoPro or borrow/rent a chassis ear from a friend or shop. Center support bearing on the driveshaft is a common cause of freeway speed vibration.
