voltronic:
Yes I understand that principle, but you're talking about resonances that those instruments are capable of actually producing and / or influencing in your room. For high frequencies, I could see this product having some kind of effect. But the article would have us believe it can also violate the laws of physics. Did you read the part that claimed those tiny resonators somehow were able to absorb / cancel the subwoofers' output? There's no way those things with relatively very high resonant frequency can influence such comparatively huge wavelengths and low frequencies in any significant way. The simple explanation for what was heard in that part of the rest is that someone swapped the polarity on one speaker. Or the little cups are magical.

I love the resonator in the car... Like its going to make a difference when your car produces a ton of road-noise! I think my pine tree smelly thing does an equally good of a job making the music sound better! LOL!

Placing a properly tuned resonant system in a room can counteract a resonant acoustic energy mode, making the room response flatter and more accurate. That's how Helmholtz cavity resonators and resonant panel bass traps function. But those kinds of devices are built to work at specific frequency ranges with rather narrow bandwidths and only work properly when tailored to suit the specific resonant problem. Measurements are required and well understood acoustic engineering principles apply. Of course no one is even attempting to measure those silly little magic cups or use them in any kind of reputable way, although they could be measured to determine their actual acoustic behavior. Like voltronic notes, those tiny cups will be physically incapable of having any affect below a very high frequency range due to the length of the wavelengths involved.
There are two small helmholtz chamber resonators molded into the plastic intake system of my Mazda which aren't that much larger than that little trophy-cup thing pictured on the dash. Of course they are accurately sized and placed in the intake to counter buzzy acoustic intake resonances (or alternately, the Mazda design engineers may have placed them there to enhance certain cool-sounding 'vroom-vroom' resonances).
Terry, those pine-tree air fresheners make the RepoMan soundtrack sound incredible!
Just ask Miller- "There's one in every car, you'll see"

How 'bout some magic pebbles to go with yer fancy ethernet cables and resonators? (No affiliation!) > http://www.machinadynamica.com/machina31.htm
If you like those, there's also a bridge I can sell you. ;)

Tacoma narrows? That was an unfortunately well-tuned sympathetic resonant system.. obviously suffering from the lack of a few well-tweaked tiny metal cups and pine-tree air-fresheners.
