If you don’t need to secure the speakers onto the stands, these Kanto stands are nice:

I really like mine, nobody notices them and they are solid.

Have to admit the sanus look better than expected. Ideally I want something with some wood finish to it though and I’m concerned about how well my Fives will balance without a clamp

My Five has been up there a long time with no issues.

They offer the ability to secure the speaker to the base using a 3M Command Strip.

I decided not to do that but if I did I’d look at the Velcro picture hanging 3M strips.

You could get a wood support bar look by having a local wood shop make a cover for the steel support. Shouldn’t be much work, just cut a slot in a 2x4 or glue up some inch lumber. Might even do it at home if you are at all handy. A base cover wouldn’t be much work either.
