Spikes or Spikeless


I have a Basement floor with 2 layers:
Carpet
Padding
Concrete...
Will the spikes drill down thru the 2 layers and rattle on the concrete?
Should I get some kind of Puck for then and would this be the same result as "wood"...??
thx

Wow - Someone put a lid on this open can of worms...=)
Thank you for all your input - I will give a few ideas a try: Im thinking try the Spikes to the concrete and see if that works. At 50# each I just did not think the spikes would "penetrate" into the concrete and perform properly. The idea of the spikes is to hold the speaker stationary. I was afraid they would "slide/vibrate" around. I will update on how much a PITA it is or was not...and my conclusions
I have a concrete floor with vinyl flooring and a rug over it. My Gamut L5s come on a base with 4 large outrigger cones; they also have cups for the cones to rest in. My two friends and I have listened to them several times with and without the cones resting in the cups and everytime we decided that they sounded better with the cups. YMMV.
I've had good luck spiking , only time it made things worse was on a springy floor that seem to resinate . The spikes will not harm the carpet .
Mine is a tad different still. Just berber carpet glued to the concrete floor, no padding. My Paradigms need the spikes to sit solidly and they sound better with the spikes, no question. My Aerial 10t, with the Sound Anchor stands mind you, sound the same no matter if spikes are used or the heavy rubber feet. My horns are too big to care. In fact, the bass horns were designed to acoustically couple with the floor so they need to sit flat.
