I do not recommend the side configuration stands for the Martin Logan SLM speakers. Center channel fell on the concrete floor while I was gone the other day - it's been sitting in the same spot for months
So I upgraded to the
XL versions (FL/FR/FC) and plan to move the smaller speakers to surround (RR/RL + RC - if the one that fell still works) Also picked up a second identical sub for $500 at a floor model discount
