The stands are plenty sturdy with the small adams atop and thats even on carpet i did consider filling the stands with sand for ballast but i dont think its completely necessary in my ca

Excellent purhcase exactly as described good quality easy to build up excellent service of delivery good vibration control

Excellent for the money like the fact that they give you options on the bottom and top of stands

The small round platforms that the spikes sit in are great as it means the spikes dont puncture the carpet
