How important are speaker spikes and decoupling?
In an ideal world the speaker would be decoupled from the room using a slab of dense material such as concrete or marble, which is in turn decoupled from the slab using spikes or bluetack. However, in the real world this is hard to achieve, and will have limited effect on the sound quality unless a considerable amount of money has been spent on the system and the room acoustics are good.
