The Genesis 44 was shipped with a simple base or stand that tilted it back a bit. This was a generally good idea. It time-aligned the two active drivers somewhat, and also broke the speaker's parallels with the room boundaries. However, in some rooms they sounded better without it.

I recently had a chance to get a close look at one, after all these years, so I took some quick measurements and photos for people seeking to make their own.

It is an irregular octagon, cut out of an 18" by 9-1/2" rectangular piece of 3/4" particle board. That length and width are cut down symmetrically to 12-5/8" and 4-3/4", respectively. I did not measure the angle resulting from that, or the length of the four new sides.

The cleat at the front is 11-3/4" long, 3/4" thick, and about 1-1/32" tall in the front and 7/8" in the back.

It is held in place with four #10 fully-threaded wood screws, which were, if I recall correctly, 2-1/2" long in the front, going through the cleat, and 1-1/2" in the rear, lining up with pilot drilled holes in the cabinet.

The stands had four simple hard rubber feet. I do not remember if they were nail-in types or stuck in place with glue.
