Telescope,
I am leaning toward Sound Anchors custom Be-718 23" stand. They advertise them as acoustically dead. Prefilled. The top surface is 7.75"w X 14"d that is almost entire base of the BE-718. It was hard for me to find a stand w/ big enuf top plate. BE718 is pretty big.
If you want to bolt Be718 to stand, Core reply to me and told me they can redrill their top plate to fit Be-718, provided that you give 'em the measurements.
But i was considering using Audio Points in between Speaker and stand. http://www.starsoundtechnologies.com/2ap7d.html
My ear level is about 36" off the ground when i sit in my chair. w/ 23" stand, spikes, Audio Point, would put the tweeter at my ear level.
i'm in process of rearrange my entire house to make a Hifi ONLY room... but stands are a must! My 10year old BestBuy stands are not getting things done!
