Question KEF S2 stands alternative?

[joeyd2548]

I just bought a pair of lightly used KEF LS 50 Meta speakers for $900, and I WOULD LIKE TO AVOID SPENDING another $450 for the S2 metal stands made by KEF to support the speakers. The LS 50 Metas have four bolt holes, 1 in each bottom corner to connect the speakers to the stands.

Does any other manufacturer make stands that will match up with these holes? Any ideas would be appreciated.

Thanks in advance,
