Thiel CS6

I use spades and I crank them down good and tight. Good to periodically recheck them with a wrench.

If the floor tends to vibrate, the spikes could exacerbate the problem, if floor the doesn't tend to vibrate, the spikes should improve things.

You're right.. Also I see how Mr Thiel developed these Speakers. Which is how it should be. He knew his music and it shows that if it's a great recording, it will sound great. And a bad recording will sound really bad. And you see when I'm in the studio and I come home. I wanna make sure it's right on target.When submitting new songs you only have one shot.And if the recording dosen't have the emotion that makes you wanna hear it again. You're dead in the water... Thanks for your input..I must tell you that setting up these speakers wasn't easy. In matter a fact I almost threw in towel. So I lQQked at the manual and put the toe in just like Mr. Thiel had it. AND Thank God, IT WAS MAGIC.So before I put the spikes on now, thanks for your valuable information. I'm going to stabilize the hardwood floors in that area. (We never stop learning)Until then.. I'm very happy. Don't get me wrong to all Eggleston owners. They're great speakers. I just didn't want to buy two subwoofers.

In response to the Theil, Vandersteen comparison.... Vandersteens can more accurately be incorporated in the room. This may very well make the Theil good or not so good in comparison.

Stringreen, I would suggest that is true of the higher end Vandersteens, but at the lower end the opposite is true, with their respective subs all bets are off.
