If you happened to read my thread about my new LSiM705's you might remember I was less than pleased with the stability of the speakers. I think a $3,000 pair of speakers should come with outriggers, or at least make them available separately from the original manufacturer. Anyway, about the only place I could find generic outriggers was SoundCity:
I purchased a pair of their P/N SEC7 and a pair of their P/N SEC9 as the plinths of the LSiM's are wider at the rear than the front. After installation, and if I had it to do over, I would simply get two pair of P/N SEC7. I believe they would look better and be just about as stable.
I was able to keep from modifying the speakers in any way by purchasing 8 nuts and bolts to go through the holes where the original spikes were. I could undo this modification in about 5 minutes and the speakers would be as new. They are still adjustable from the top like the stock speakers are.
These speakers are VERY stable now. I'd say they are close to impossible to tip by a dog or child now.
