Too bad B and O does not make some sort of riser for them. :)Simple solution, make (or get someone) a stand of what ever height you require.
I had two black polished granite stands made to put under my 8000's, it was for visual reason's. They were only 1centimeter wider than the base of the 8000's and I had the edge chamfered to mimic the foot . Of course you can make them from wood metal etc.
I have thought of that. My concerns/questions are 1. how high would I need to to raise the 9s? Just high enough to get the tweeter above the furniture level, the mids, or the entire speaker? 2. Depending on high I need to get the 9s to, a solid speaker base of granite, or even wood is going to get to be extremely heavy. If the base is not solid, I am afraid it might affect the sound quality?
