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'm thinking of something like a heavy duty plate with four solid
fittings above and three below. I suppose an alteration to the sound
is inevitable but would avoid scrap the idea if it has too much
effect.


An alternative is to put paving slabs on top of the carpet beneath the
speakers. They should be heavy enough to not move and also present a
more uniform surface for the speakers though even that would not be
perfect. The slight problem here is the slabs sold by the local stores
are fairly lightweight.


Any ideas?

Widening the net a little....

I'd agree that three spikes are rather more practical than four. But afraid
I don't know of any kits for the below.

TBH I have my doubts about such 'slabs' under 'spikes' being of much use.
Have a look at http://www.audiomisc.co.uk/cones/speak.html to see why I
have doubts about that. You might be better with a layer of something
squidgy like 'Blu Tak' between speaker and a heavy slab. Or just don't
bother. I've missed the previous parts of the thread is this is the first
posting on this thread I've seen, so I wonder why you think the 'spikes'
are desirable at all...

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!

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.

Why do you want to move them around so much? Take the spikes off, experiment
with positioning the speakers for a week or two. When you're satisfied they're
optimally placed, put the spikes back on and leave them on and be done with it.

I think the reason for four was health and safety actually, harder to wobble
them over.

By audiophile reasoning, would just ONE spike, perfectly balanced, be
the ideal? :-)

Wobbling over has nothing to do with the number of points of support but is
to do with the geometric relationship between the various points of support
and the speaker's centre of mass/gravity/momentum - pick whichever takes yer
fancy....

What do you mean by 'audiophile'...???

IIRC, WW Greener's formula was that the projectile to be fired from a rifle
should not exceed that of 1/96th of the rifle's total weight (mass?) -
whether a speaker would need coupling to a firm foundation would depend upon
its overall weight (mass?) I suspect....

O yes, it has to be gold plated, have directionality marks for gravity,
cosmic and magnetic influence, machined to 1 thou of nothing, made in a
total vacuum - and have an impressive price. Probably needs degaussing
regulary ...
