I'm designing a simple speaker stand. My question is: if the speaker will
sit on a kind of spring or rather if the whole stand is a slightly
springy-like, will this somehow affect the sound coming from the speaker
compared to if the speaker was on a heavy and solid object? This stand is
not necessarily for high-end use, but certainly hifi, or at least I hope
so. So should a speaker stand be very solid to prevent vibration of the
stand. The speaker's weight is about 6-8kg.

ps. If you know any nice looking short, about 40cm high speaker stands,
I'd be delighted to check it out.
Do not put the speakers on springs. Speaker cabinets are not inert. They
vibrate. In the case of a strong resonance, the level of sound emitted by
the cabinet approaches that emitted by the driver. A good support system is
not springy.

Physics tells us that the speaker stand should not be perfectly rigid
either; it should be mildly deformable, with very high "loss", ie, it should
convert vibration into heat quickly. However, I am unaware of any commercial
speaker stands that attempt anything more than complete rigidity.

But certainly do not go for springs! Don't try to bounce that idea around
