Is Spiking Necesarry?

I stopped using speaker spikes years ago when I found that simple and inexpensive Vibrapods (I've had suspended wood floors in listening rooms for many decades) keep the energy from the speaker from going into the floor and coming back into the speaker…many modern high end speakers have adopted something like this…also custom feet with some sort of suspension/damping can also accomplish this but at a far higher cost than Vibrapods. Currently (and with my previous speakers) my speakers are on butcher blocks with "pods" between the blocks and the speakers…works for me.

I would consider Vibrapods "spikes", albeit loosely defined. They appear similar to the Herbies Gliders.

Put your hand on the floor (suspended, not slab) next to spiked speakers paying dynamic music with plenty of bass content and you can feel the vibration on the floor…do the same with Vibrapods (or other things that turn vibes into heat…like my cousin Shirley) and you should ( or will) feel zero vibration from the speakers. That’s the difference. Also, it it necessary to know how to spell "necessary?"

My problem with spikes and footers is that every time I've ever raised my speakers using them - and that includes several different speakers - I've found a change for the worse.  The  upper/lower bass tends to start bloating a bit more.  Whereas simply sitting directly on my wood floor (actually, sitting on a shag carpet over my wood floor), with no spikes, the sound stays tight and clean.  I don't know why.

Right. I get it. And true in your case if this is your experience. However, I'm not convinced (granted I haven't tried) that would necessarily be the case with my speakers on carpeted wood flooring, and more importantly whether or not it *should* be the case. I think what you're referring to would be a complete "decoupling" from the room, and I'm not sure speakers that are producing low bass should necessarily be completely decoupled. But I'll conceded that "pointed spikes" in the traditional sense (like still points) may be less desirable than the Vibrapods in certain applications.

And this is why the most appropriate answer to the thread title, with the assumption "necessary" implies improved sound quality, is "it depends".
