Tweeter height - how to compensate?

My new speakers are too tall! The tweeter sits about 6 to 8" or so above my ear when I sit on the couch. This is really my first true experience with conventional speakers as I previously had Maggies, where tweeter height is not an issue.

Besides changing the furniture (not an option - and anyways, the sofa would look ridiculous - the one we have is already of a decent height), what else can be done?

I have tried raising the rear of the speaker a half inch or so but it sounds like this broke up the soundstage or something - I did not like the sound even as much. The speakers sound good but walking around and just before parking butt they sound better.
