Acoustic resonators in place of room treatment

Attended Frank of Acoustic resonators demo during Kuala lumpur AV show , Malaysia yesterday. Demostrated his magic show and I can really hear the difference . During Q & A session someone asked him whether it is necessary to do room treatment if we use the acoustic resonators. Was told it's sufficient to use only the resonators up to max 11 pieces only. I got my room treated using Rives level1 ( only level possible in Malaysia) & faced with construction issues & it's only theoretical design only. If it's truly work , it's certainly preferably over traditional room
treatment. Cost wise it's comparable . Anybody has tried the resonator method of room treatment & what is your impression?

That a resonating cup will make a sound like a wine glass or a bowl there is no doubt.

Why you want more ringing I am not too sure. I spend much time trying to get rid of spurious resonant sounds that are not related to the music.

The large fins on the heat sinks on my amps also make a sound when there is music playing - which is why they are best kept in a cabinet reducing the ringing by a further 30 db and making the ringing all but inaudible. Doors, windows and wall hangings can still rattle but you can only go so far...

Has anyone tried egg cups?

Is there any reason why acoustic resonators have the market cornered on all metal cups/bells that resonate audibly and improve room acoustics?

After all, to extend the analogy, Rives only does professionally with more know how and expertise than what DIY'ers can also achieve with fibreglass chunks etc....i.e Rives follows well known acoustic principles and science...

Of course, everything would depend on what that resonant frequency would be as well as what resonant frequency would contribute the most. Everything would be trial and error.

Correct - I was thinking of a metal egg cup for enjoying your boiled egg.

I agree about trial and error - which is the exactly the same issue for DIY acoustic treatments ....you build some panels and then try them out and find a good position for them.

It occured to me that metal or ceramic egg cups, bowls, bells, thimbles, wine glasses, abalone shells, chimes and other similar items must necessarily behave like Acoustic Resonators so why haven't people tried them? (Note: There is extensive experimentation with DIY acoustic panel stuff from heavy curtains to shaggy rugs - so why not the same DIY solution with "acoustic resonators" ?

Please don't tell me there is a quantum dot or something super special ONLY about Frank's version - surely there are other resonating things out there that might work too?

Anyone try five crystal wine glasses strategically placed on tables around the room?
