Hi all,
I just wondered if this would be workable as speakerstands and influence the roomacoustics as well? I thought if one has a problem with a certain frequency one could build them accordingly, put Rockwool in them and saved space in the CR as well.

Is this "real-life-qualified" or just a nice thought?

Thanks

Hello Dreamer,

Just an untested thought/guess.
I really shouldn't do that.

The basic idea of a speaker stand is to keep it stable and neutral.
Making it a resonator close to your speaker doesn't feel as a good idea.

Hello Eric,
I think this would be stable cause you can get big tubes of thick and pretty heavy particle board. And the bottom- and topboard could be of different marerials. I assume statics wouldn't be a problem. The carpenters among you may correct me if I'm wrong.

But would it have a reasonable acoustical effect?
Maybe you're right and this is a brainfart - just an idea one can think about.

Greetings

BTW, recently I read an article in the german Studio-Magazin about the Galaxy-Studio in Belgium. I assume that it's you, Eric, who was hired there for acoustics. At least this guys name is Eric Desart. Very impressive - a mammuth project

I still shouldn't do it. It's not about the statics.
You create an Helmholtz where the surrounding air is part of the resonator.
In fact you set your speakers on top of a tuned vibrator.

You can test it, but for me it feels wrong.

Eric

PS: Yes I did Galaxy.

I think I (with my humble acoustics-wisdom) do understand what you mean.
Thanks for the insight.

When I come up with my next brainfart I will approach you again.

Thanks

By placing the resonator close to the speaker, much shorter than it's tuning wavelength, you are essentially EQing the speaker output. This isn’t much different than doing it electronically. And we know that, except for wavelengths very large compared to the room dimensions, EQ isn't effective at solving room acoustic issues.

In the worst case you could actually reduce the acoustic loading on the speaker port and/or cone, causing problems with their response and/or stability.

So yeah, I agree with Eric. This probably isn't a good idea.

Thomas, thanks for your thoughts!
Would have been nice if it has worked....wishfull thinking
