There are two stand choices when you buy the speakers. L-brackets (which mount to the back of the speaker frame) and some kinda oval base thing (which mounts to the bottom of the frame). The ovals are a couple hundred dollars more expensive. (Not a fan, but that’s neither here nor there.)
Regardless of what stands you choose, the speaker frames are drilled for both.
The magna risers mount to the back, into the same threads that the L-brackets would go.
I built some quickie ones out of walnut. They mount in the back, just like the magna risers.
