acoustic system resonators

Sorry, I had not recalled that.

I grant that explanations of how it functions cast suspicion.

Here is the test data that you request:

The fact is that resonators work and two different sets of reviewers from two different magazines both hear and swear by them.

Why don't you non believers try them and see for yourself you might be thrilled with them.

Most electronic processing is not built to the same standards as the high end components that most of us are using.

I came across what may be a reasonable explanation for the possible effect of Acoustic System Resonators - it seems that this kind of devive may produce multiple harmonic overtones at the same time. Similar to what happens if a tube amp is overdriven but different becuase it does not necessarily add richness to a the note played...in fact it is multiphonic and polyphonic (adds many notes - quite different from a bell).

Of course, this is passive - so it may only respond to excitation by the sound waves in the room, however, given our huge hearing sensitivity (0 to 120 db spl) and the fact that a subtle sound from a ringing cup may be audible between loud notes when music is briefly quiet then it may add something.

What will it add....if you read my link above then you will get an idea...this type of thing is used in meditations by monks...so atmospheric kind of shimmering quality is to be expected.

Is this audio reproduction - no, not in my mind but it may have an audible effect and that effect may be pleasing to some people. YMMV

Since I have to take apart my system tomorrow for my building to jackhammer through our floor, I also want to take my Resonators down off the wall. If I have time I'll try to do a quick listen with the Resonators then without them.

I've liked the results with them in the system in the past, but my system has gotten alot better since I did the test many months ago when I first got the resonators. Actually in that test, when I pulled them out I didnt hear much difference, but when I brought them back into the system, I definitely heard improvements. I have at times removed just the rear one and heard the soundstage become more collapsed. The effects were not astonishing, just nice.

These resonators are not cheap, but they work !
The discussion how they work and which audible effects they should or can have is quite interesting, but you only can trust your own ears.

Clocks, pebbles, teleportation, and resonators.

Step up and buy your snake oil.

Caveat emptor.

sad to say, these work!! dont know how, but they work as reviewed in six moons and others... yup, i',m a believer!

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).

Peterb, I assume the back wall is behind the speakers. Were I to position these eleven resonators as you suggest some would have to be on windows and cabinets or book shelves. Is that okay? Also those behind me would be behind shelves of records. Okay?

I have tried many room treatments. I have used RPG diffusors, Tube traps, Room Lens, Acoustic Mirrors, Shun Mooks Mpingos, and presently Shatki Halographs, which are the most successful. I have also done digital room corrections which were the worst. I have also used Brilliant Pebbles and Acoustic Revive Quartz Resonators and still have some Harmonix room treatment pucks on the walls. The Acoustic Revives have been very effective on the speaker wall and the windows on it.

I have found great interactions when using several of these devices at the same time. Presently, I can only use one pair of the Halographs, seven of the Shun Mooks, and the few Acoustic Revive Quartz Resonators on the speaker wall. My H-Cat P-12R line stage has a very effective Wave Timing Control that greatly affects the sound stage and realism of the image. I particular the Halographs, Mpingo Disks, and Brilliant Pebbles fight with the H-Cat's WTC. I imagine that the Acoustic Resonators would also.

A Sound Level Meter can determine locations in the room for resonators with better accuracy in many cases than following general instructions or the old "move and listen" technique. YRMV.

I think only a Tricorder can help with this level of complexity;

Shadorne, of course this has been over a 20 year period and usually with one device tried at a time. Once about a year ago, I removed every room resonance device and adjusted the H-Cat. Only then did I seek to reintroduce the resonance devices. If they helped, they stayed.

Tbg,

I figured it was a bit more sane that it sounded in what was a probably a quickly typed response...I just could not resist suggesting Spock take some Tricorder readings ;-)

When setting up a sub for the first time I often feel like calling Scottie and askiing him to beam me up new dilithium crystals....this hobby can be fascinating but it can be a challenge sometimes. Peace ...

Tbg,
The back wall is behind the speakers indeed.
The cups should be resonating freely, standing on their wooden bases, and the surface they are attached to doesn't matter. The position of the resonator in the room (in relation to speakers and listener) has far more influence.

Peterb, did you see the follow-up review on 6moons? I went to the international distributor's webpage also.

My guess is that they would interact with my Halographs and Acoustic Revive Quartz Resonators. Of course there is no way of knowing beforehand. Were I able to try them in my room, that would be great. But alas that is very unlikely.

Link does not work for a long time. Do you have this document ?

Maximus_lt, Virtual Dynamics is now High Fidelity Cables http://www.highfidelitycables.com/reviews.html

I have no idea whether they continue to have the test data you seek.

I found a new link if you are interested: http://www.avataracoustics.com/acousticsystem/pro_link_test_report.pdf
