To spike or not to spike… that answer is going to be all your own.
A multitude of threads here have so many varied themes and practices there’s legitimately no one particular solution. No ‘one size fits all’ remedy.
The only general aspects to speaker integration I’ve found that continues to materialize regardless the brand or model is….
Spikes are better than no spikes.
Bigger spikes are better than little spikes.
With really thick carpeting, a platform between the carpet and the spikes works better than trying to get thru the thick carpeting…. Looks better too.
The type of platform (if one is used) does matter/alter the sound…. Somewhat.
Different woods have different audible characteristics…. Rosewood, zebrawood, Teak, Ebony, Mahogany, etc.
Once any of these are set beneath the spikes the tone can be changed or altered.
Hard = hard sounding
Sofft = softer sounding
Placing speakers on hollow wooden floors (upstairs etc) is tuffer a thing to do right, than those placed onto immediately and better supported likewise floors usually a plinth or platform will work best then.
What you need to do is just try different things. I tried as many inexpensive things as I possibly could. I’m satisfied for the moment with the sound I’m receiving.
Is there a better way still? Probably. It comes down to you though. Another thing to bare in mind is this… after trying out a good many methods and you still aren’t happy it might well be the speakers…. or you instead of how you are integrating them into the system… or a simple lack of synergy between the speakers and the balance of the audio outfit…. And/or their integration into the room itself.
Don’t go crazy here… but ya gotta see for yourself nearly explicitly here.
Good luck.
