Speaker spikes on concrete or wood floor best?

No Spikes.

Ever.

Not turntables and definitely not speakers,no matter what is claimed for them.

At least not where compellingly musical sound is concerned.

And concrete is vastly inferior to wood as as surface to support real music.

Should have said IMO, even though it isn't even close.

My reasoning is simply from listening.

Everyone who hears the comparison always agrees. A lot of head shaking goes on as people cannot believe they been led to believe this myth.

The sound goes from tight "audiophile" bass to realistic sounding bass with proper form, attack, and beauty.

One of the most successful high end companies does this, and it takes about five minutes to convert them from mechanical sounding 'precise' speakers to something that actually produces music.

I have no idea why they use spikes. Makes no sense whatsoever.

Even the expensive products do it - to their considerable detriment, IMO.

The improvement in the musical results are mind boggling when this old-wives-tale get addressed.
