Anyone here who has installed floor spikes on the larger floor-standers? I'm talking L220, L150/A, L250, etc.

My L150A's have to sit on thick carpet, and always start to lean forward quite a bit. The boxes under them are perfect for installing a couple 2x4 rails and some spikes. Questions of audio quality aside, this would fix the leaning issue, as would a set of outriggers with spikes.

Question: Has anyone gone this route? If so, what was your impression of the differences in sound? Mine would be sitting on slab with carpet and pad.

I also considered making some simple plywood or steel platforms with spikes, that the 150As could park on. This would make moving them around a lot easier than having spikes in the cabs.
