Best location for isolation cones.

Just got 4 sets of Dayton Audio Black Chrome Isolation cones delivered yesterday.

Due to the space constraints on my rack, i couldnty put em under the gear like i had intended, instead i put them beneath each subwoofer which gives righter more defined bass.
However, i also put a set beneath each speaker stand. I also have a new rack.

The imaging seems to have suffered a bit. Are isolation cones beneath speaker stands a bad way to go? Seems the imaging was a little bit better before i put them into play, but with the new rack i just put in im not entirely positive which is giving me a hard time

Ive never used these before so i dont know if there any big NO-NOs associated with such a thing.

Any advice?

Placing a cone under the speaker raises the height of all drivers, which affects voicing. IMHO, the result has zilcho to do with isolation, and everything to do with geometry. If you have precision engineered speakers, such as Green Mountain, Meadowlark, Theil or Vandersteen, recommend you not change the height of the drivers. Get a listening chair that levels your ear with the tweeter. Raising the subwoofer a smidgen is a whole 'nother story.

Jburidan: Keeping one's ears level with the tweeter is an old wive's tale. Some designs work best with your ears above, some below, some sitting even with the tweeter. This has to do with the cabinet design ( acoustic center of the drivers ) and many other factors. Even if listening with your ears even with the tweeter provided the most neutral tonal balance, who's to say that everyone would prefer this type of "neutrality" anyhow??? Obviously, personal preference plays a large part in what people buy, how they set it up and what they like to listen to. Sean
