Several things going on here. For starters its vibration control. Can't be isolation because, well imagine perfect isolation: speaker levitating, just floating in space. But the speaker, in order to make any sound at all the drivers have to move. F=ma, every force needs an opposing force, the isolated speaker has only its own mass. Total flop, drain all the energy, a fact proven as easily as putting the speaker on an inner tube or even a couple sheets of sorbothane. So forget isolation.
Vibration control. Forget grounding. That ain't it either. As you can prove as easily as trying different shapes and things between the speaker and the floor. Which I highly recommend. The only way to eventually reach the point where you have a clue, have actually learned and are no longer merely repeating dogma other people repeated to you, round and round ad nauseum, is to try it. My tagline: go and listen.
Okay so by the way all the above applies to everything. You asked about speakers. A speaker is also going to sound different merely being raised or lowered an inch. Everything else the same but that inch changed the room reinforcement and relationship between you and the speaker which also affects the response you hear.
So these are two separate things- vibration control and speaker placement. Try not to conflate the two.
Third issue- subwoofer. Every speaker is better with subs. Even a system with subs is better with subs. Mine has five. It sounds a lot better with five than it did with four. It sounded a lot better with four than it did with one. Understanding the theory behind why this is so I have no doubt six will sound better than five. Do a search for distributed bass array, Swarm, or read all posts by Audiokinesis if you want to get up to speed on subs.
