Default Speaker stands from reinforcing steel?

Hi guys,

I'm thinking about building speaker stands welded together from reinforcing steel. What are the potential problems and (how) can they be solved?
The stands would need to carry two different types of speakers, 11kg and 26kg.

Thanks.

Tube or solid? Round or square?

Do you have all the necessary tools and skills?

Oh OK - we call it "rebar" here in the States.

What sort of problems did you think you might have? I can only think of the possibility of the bars vibrating, but i have no idea if it would be audible - my instincts tell me it won't be.

However I'd recommend you not place the speakers directly onto the metal - make bases out of mdf and place the speakers on those, either with isolation spikes or rubber feet, etc. You should probably do the same thing at the bottom, but that depends on what the floor is made of - solid or carpet.

It will be hard to avoid making a mechanically low loss structure out of this material. Maybe if you finally cast it in rubber or something.. Concrete?

and, best not to have too much iron close to Xover

and needs a complicated construction to make i stable

hmm, might look special with lots of it welded close together side by side
and it would be stable

I'd like to have it as lightweight as possible but the questions is if a rather flexible construction with rubber damping between speaker/stand and stand/floor is desirable?

Here's an idea how the stand could be decoupled from floor and speaker:

No reason for them to be light weight - they should be robust and relatively heavy.

The worst case scenario would be a speaker hanging from the ceiling. Is this detrimental to the speakers performance?

I prefer mine to be heavy just for safety. Don't want them to get knocked over.
