This may be viewed as sacrilege, but let me ask you anyway: Does the Orangutan produce images at a height you find satisfactory? If yes, nothing more need be said. If no, here's a radical idea you could consider: Make stands for the speakers that raise them to a height that results in them producing the image height you desire. Yes, the time alignment of the drivers will then be not as designed, but the enclosures can be tilted forward until the driver alignment is restored to factory. The image height will be raised, but the speaker sound will as intended. That is, unless the boundary effect of the floor was a design element in the voicing of the speaker, a very real (perhaps even probable) possibility. In that case, if you desire a higher image you'll need a different speaker.
