> What's the best approach?
Passive vibration isolation works when the resonant frequency of the vibrating component connected by some stiffness to the structure is well below the frequencies you want to isolate. So if you have a speaker generating deep bass of a few tens of Hertz then you need a resonant frequency of a few Hertz or lower.
Suspending the speaker on bungee straps from the ceiling would be cheap and effective.
Sitting the speakers on top of a spring will be less effective because the short distance will dictate a stiff spring.
Wrapping long bungee straps over pulleys attached to a framework would enable one to get soft springs with a standlike structure. It would probably not be difficult to make if you are DIY inclined.
Active vibration isolation is the most effective but is expensive if you are isolating heavy objects because you need to generate large forces.
