Hi,

Looking at the attached photo of the Sony SS-AR2, you'll notice that there are wood braces at the top and bottom of the cabinet.

Are these braces useful, either theoretically or in practice?

Thanks all.

Don't be shy...tell me more please.

i always do that, glue all the leftover pieces of wood on the inside of speaker panels...I am not sure if it helps theoretically or practicaly, but I do it anyway. What else can you do with odd cuts of wood? You can burn it, throw it away, or use it to make the box heavier and less resonant.

I would go further. Your cabinet can't be too stiff. Here is what I did. Notice the last shelf brace is itself braced against the end panels. Don't use mdf for bracing. 1" ply is much stiffer after cut-outs.

Have to be shy as this is a hush-hush project and I've been sworn to secrecy.

Using 19mm and 30mm BB ply. BTW those braces are a work of art.

In my quest for stiffness (sounds like an adolescent dream), I'm worried about too many braces causing a significant reduction in volume.

Cheers.
 
A further thought; these Sony speakers are $25,000.

Knowing the attention to detail that went into the design and manufacture of these speakers, and the extensive bracing inside, surely the designers would have to have a compelling reason to include the top and bottom braces? And wouldn't they have oriented them the way Planet 10 suggested?
