acoustic system resonators

It's all in your head.

If you want to hear a difference, you will.

Fantasy audio.

Two edge sword. If you don't want to hear a difference, you won't. But I am sure you knew this.

Audiofeil, I get the impression that you never did hear these resonators yourself. It's very easy to convince a listener with an open mind, that these resonators work. If this person is willing to pay the rather steep price, that's another question.

Peterb, did you have to move the Acoustic Resonators around to find the optimal spots? Which ones did you use?

There are guide-rules for placement (eight steps):
1. Position a resonator on the back wall, exactly between the speakers, 30-60cm above the tweeters
2. Position a resonator above the first one (between this and the ceiling)
3. Position a Basic resonator right under the first one, around 15cm above the floor
4. Position two Silver resonators on the side walls, next to the speakers, same height as #2
5. Position two Silver resonators on the side walls, next to the speakers, 15-40cm above the floor
6. Position two resonators on the side walls, same height as #1, next to or slightly in front of the listening position
7. Position a resonator right behind the listener, same height as #6
8. Position a Basic resonator right behind the listener, 15cm above the floor

I'm using:
#1=Platinum
#2=Special Gold
#6=Special Gold
#7=Special Gold

When I remove all cups (and I have showed this to a few audio-friends) the soundstage collapses completely (in width, depth and height).
