Speaker stand makers - Tannoy Turnberry

there are a number of usa stand makers that can do this for you, albeit at a cost

just search on ebay (where they advertise basic models) ... at least three will pop up, one in az, one in colorado, one in tx

all with decent reputations

Local cabinet maker is the best route.  Etsy also has offerings.

Very simple to make them yourself. I made some about 8 inches high for a friend using douglas fir and birch plywood and stained them with a mixture of Minwax Early American and Walnut stain. The cost was less than $30 and took a few hours to construct. The construction consisted of 4 3x3s from 2x4 douglas fir glued together and trimmed to 3x3 on the 4 corners held together by an internal box of 3/4 inch birch plywood. Once stained and sealed it matched the speaker veneer perfectly. 

Here is a picture of stands similar to the ones that I made:
