The front base of the speaker should be approximately six inches off the ground, plus or minus maybe a quarter inch, depending on how the feet are set up. I didn't measure the rear height, but the stand is built with an approximately 3-degree slope from front to rear. The angle was calculated to get me into the main beam of the vertical directivity based on my listening distance of twelve feet, if you're deviating significantly, you'd want to recalculate the angle to fit. I've since moved the couch a foot closer, but the vertical directivity is sufficiently wide that I and several other listeners agree that there is no discernable difference in listening tests from either position. Regarding what the rep told you, that does not align with my experience. All four sides and the back are a high gloss veneer, so unless he's talking about the front being aluminum, I'm not sure what he's referring to by unfinished. I think some of these may qualify as B stock, there were one or two imperfections in my center channel, as
@amirm called out in the review. The feet are removable, I knocked one of them off sliding it into the stand and it did not mar the finish.
