They are ribbon speakers.
The ribbons extend down to within 500mm of the floor, well below ear height unless you are in a semi-comatose collapsed on the floor state when it's far too late to notice!!
The overall height of the stands is less than 4".
Even when I had stand mounters (Epos 14s) the improvement through using the bases was far greater than any problem with changing the height by a small amount.
What do you get from a change of height? A difference in the balance between the high and low frequencies. Yes, but the question is how much, which is a tricky one to predict.
Now I tend to have the speakers set to produce good sound across the wide stage rather than to focus directly in to the sweet spot, so I think I may get less of the problem then if you have that other arrangement.

and it's a traditional 3-way... he's not fussed about 2-3" of incremental height. Just FYI - probably worth checking with the speaker manufacturer before designing the platform.

  ... from the floor, is that at first the bass may sound a bit light because you are losing all the reinforcement of what is probably upper and mid bass.
  You will lose some slam from a lot of records. But what you will gain is a much quicker bass. And in my experience, the deep bass will come through clearer as it is not being obscured by the bloated mid bass.
  I would suggest (and this will obviously vary with your musical tastes) some small group jazz where the bass and drums will be a major part of the music and then something with very deep bass. I have a cd of organ music that, in fact, I am not that keen on, but it does have a section I always use to check the deepest bass.
  This clearing of the sound can effect the atmosphere that the music seems to happen in and should improve and should help soundstaging and imaging.
- good idea - dave c 15:06:43 06/10/07 (0)
  Obviously, the lower the height of the platform, the less difference it will make.
  But do you have your tweeters at ear height, and where is ear height, within a couple of inches?
  If you were to use 2 layers of a board at say at least 3/4" each and a soft layer in the middle and footers, then I think 3 inches is achievable without too much fuss. 4" is easy.
  Again, I would definitely say you gain more than anything you could lose.
