Anyone heard the KR Enterprise Antares????

Wouldn't you have to use two of the Gizas? I thought they were only 10" wide.

The Gizas are 20" x 14"

That would probably work pretty well then. Cheap too!

Another support possibility is a custom sized Neuance beta shelf. You'll need four cones under it, preferably ceramic(but not necessarily, YMMV). A Neuance will bear the weight and probably offer pace & clarity into the bargain. (costs less than $200, I believe).

Where do you get the Neuance? Do they have a web page? Also, I remember now what my concern was about the Osiris. I once cosidered for my speakers. How wide are the Gizas not incluiding the extruded supports? If it's 12" or less, I don't know that it would work.
