Is Spiking Necesarry?

What is the general consensus if any, on speakers sitting on hardwood floor in room above basement. I guess this is called hanging floor but I'm not sure. What about some kind of a damping material between the speakers and the floor?

I'll try the concrete slab idea and can put a few felt pads underneath to avoid scratching the wood floor. For now, I've put some isolation control pads - 3'x3' square 1' thick cork sandwiched between rubber, under the three ends of my 2Ci speaker metal stands and the bass is a little better controlled. Reinforcing the floor from basement ceiling is a good idea too. I'm guessing this is a common home construction style in northeast US or homes with a full basement.

I think this (spike) discussion is all over the place because we are mixing the applications. I always thought the spikes were provided for people who place their speakers on carpet floor. This way the speakers are, 1) more stable, and 2) they cut through the carpet and bond with the floor underneath. Hardwood floors; depending on sitting on a concrete slab or on hanging wood base, pose a completely different set of requirements. My most recent experiment of isolating the speakers from wood floor using damping blocks seems to give the least distorted bass. I could literally feel the very low octave vibrations in my listening chair with them sitting directly (on metal stands) on the floor. Those who actually like to "feel" their music under their seats and might prefer a solid coupling of the speakers to the floor...
