On my new hardwood floor it must be slippery. It sounds like a creaking sound when i put the volume up. Should I put a big weight on it? It`s a Paradigm Servo 15. When I go sit on it the sound goes away. Also my floor is very "bouncy" it`s not the most rigid thing in the world so what could be done about that regarding spikes or no spikes. I currently have spikes for my main speaker stands.
