All Thiel floorstanders are designed for an ear height of 3’ and an ear to tweeter distance of 8’ or more. On a CS1.5 @ 33" tall, you can position a rod on a block on top of the cabinet to use as a sight to your ear height. A laser and target works even better. Any combination of lift and/or tilt is OK. Tilt is better at keeping the floor-bounce bump as designed. Lift may avoid obstructions better.
At your 6-7’ distance, the driver integration will be less than perfect, but probably better than many installations that haven’t sighted-in the proper geometry.
