Anyone heard of a kit to convert four spikes to three? It would have
to fit beneath the existing arrangement as I don't want to modify the
speakers (which are Dynaudio Audience 62 floorstanders).

I don't understand spikes. Audiophiles talk about coupling and
arrange heavy lumps of stone to couple to. But then they minimise
that coupling by restricting it to three or four points!

I first heard of spikes and it had solid reasoning as used on rugs on wood floors.
For cement, you need another medium to convert, like using a piece
of soft pine under each spike on top of the cement. The spike will auto level,
and provide a better impedance match of the mechanical system
That would not work either for some speakers at loud volume, and the speaker
will start to walk. Some rubber would healp that scenereo.

Perhaps the spikes are merely so you CAN adjust the speaker to stand
level on a concrete floor?

My practical experience of large speakers - some much larger than
anything found in a domestic setup - is that they generally sound MUCH
better mounted at least a small distance away from any flat surface,
wall or floor.
