Ditto to what Audio4fun stated on the benefits of marble, though I have heard dimensions of 4" additional on all sides to the dimensions of the speaker bases (i.e. 8" total greater dimension on all sides).
However, Duntech Sovereign speakers are about approximately 75" tall, 18" wide and 23" deep and weigh approximately 170 lbs apiece (I may be off a bit on these dimensions). Duntech Black Knight speakers for awhile came stock with a very heavy, dense base bolted to the main speaker similar to Audio4fun's stated method for his Sovereign.
Practically speaking, most speakers will have to settle for resting their spikes on a simple marble bass platform with the 2" larger dimensions stated by Audio4fun.
Also, I have been looking for marble for my current speakers and am finding it difficult to find a thickness in excess of 3/4". If you do find a source of a thicker marble please let me know.
By the way, expect to pay a premium for marble (or even granite). I am being quoted approximately $500 for two 25" x 20" x 3/4" slabs of polished Black China marble.
