Hi Casey,
On the "Questions" page of my website, I mention cones, spikes, etc. under the baffles as one of the possible tweaks.
But, as you have discovered there are pluses and minuses for most of them so I make no strong recommendations.
There is certainly a difference in the sound depending on the flooring material. I have always placed the speakers on a carpet ..... or at least had some carpeting placed in front of the speakers to knock down the reflection from a hard surface floor.
As always ..... your mileage may vary .....
One of my local customers uses the Nordost SORT Kones under his Betsy baffles (and just about every other component in his system).
I'm not sure which version he has under the speakers, but there are four different versions ranging from 75.00 to almost 400.00 EACH .....
They are a little rich for my retired pocketbook, but I must admit that his system sounds killer with a Decware Rachael being one of several good sounding power amps in his stable.
I have always had good success with the Herbie's products ..... so the dots would probably be a safe choice.
Happy listening,
Randy
