Quack System Upgrades

Andy, I'd feel better if we could....*L*

I want the "I don't mind Lamp"....wait a minute, I already own some.  You turn them on, and they don't flicker at me.  Unless the utility is having a hiccup, that's OK.  If I don't like white, there's colored bulbs....

Meanwhile, speaking of resonators....

Some want to do it on purpose, and pay a premium to do so.  Another "Say What?!" moment.....   Buy some ART for the room, a couple of beautifully done bowls that 'float your boat' aesthetically.  Something to 'take the minimalist edge off the cave'.  I'd wager they'd do more or less the same thing; and if they didn't, move 'em into the living room or wherever....

They're pretty...for a nicely rendered sat dish....;)

Can we blame all this on lead in the water, please?

I am truly surprised that that one didn't get nominated on page 1, Jerry. I have no idea as to its sonic benefits, but it better be more than a "I'm telling you I can hear the difference, dammit!" product at that price IMO.

Best to you Jerry,

speaking of resonators, these tiny bowl resonators have been around like forever. The first was the Acoustic Resonators, from the mind of Franck Chang, which come in pure silver, or pure gold or pure platinum. (Pseudo-skeptics alert!). There are others, too, different materials, but the same idea. It’s straight physics, right out of the textbook I’m sure you’ve long forgotten. Broadband Helmholtz resonator. Heck I’ve even got one, Codename White Poppy, named after the white ceramic I use for mine. I know a good thing when I see one.

the mind is a terrible thing to have

I built some DIY HFT resonators using ozzy’s recipe (copper fly fishing cones inside of 1/8" copper plumbing end caps). Total cost was something like $20. They definitely effect the sound in my room. Pretty powerful actually. Easy to overdo it and the mid-treble gets hard sounding IME.

I also heard the SR ART system in several settings. I like the effect but just too expensive to me, not to say that others haven’t gotten great results they feel to be worth the money.

Also heard good benefits from Helmholz resonators between and behind Apogees.

Then there are the Schumann resonance generators...heard good things from friends but concerned about health effects.

My resonators and most others like Ziplex and ART and Franck Chang's have bowl diameter of 7/8" or 1" just for reference. Now, one interesting thing about these resonators is that they actually work in two ways. One is acoustic, since the diameter of the bowl is the same as some acoustic wave wavelength. The diameter also happens to be the wavelength of some radio frequency (I.e., electromagnetic wave). Which is why placing resonators in other rooms improves the sound. The other Chang resonators, Sugar Cubes have a very small hole, maybe 1/8" diameter.

If you think the ARTs are expensive check out the platinum and gold Acoustic Resonators from Franck Chang.

Of course the orginal Argent Room Lens is a Helmholtz resonator. So is an empty coke bottle. I built a Helmholtz resonator to deal with a 70 Hz standing wave. The resonator was a 15' long folded horn with a nozzle on one end and sealed on the other end.

I immediately like the whole idea of Schumann frequency generators, but never owned one. Well, I did set up a portable CD player and small speakers so I could play a Schumann frequency CD. Would you believe very small speakers can produce a 7.8 Hz frequency in the room? 😀
