Speaker design question

[bighorn]

Assuming the internal volume of a speaker enclosure is correct for a particular driver how important is the actual shape of the box?

[Melo theory]

Have you read this thread?

Best sealed enclosure for completely supressing back wave

Or this one?

Box colourations - really ?

Maybe this one?

Sealed enclosure -- golden ratio?

I mean.....there are a lot of threads covering this.
But to sum it up, it depends on the BW of the driver.
You just have to be careful of standing waves.
Also, some shapes suppress vibrations better. Like round or egg shaped

Thanks Melo. I'll check out those threads.

To add to that... if the aspect of the proposed box is such one dimension id significantly larger than the other you can change the natural of the box. Mostly this is of concern with a bass reflex as it can turn into a Mass Loaded Transmission Line.

IOW, at some point quarter wave action will predominate - which becomes a critical factor in the design of non sealed enclosures.

Something else to consider is internal depth - I've had experiences with several wide and shallow designs that exhibited colorations most notable in the vocal range not present in enclosures with different aspect ratios - even those much smaller in overall volume.

Oh yes, I was assuming sealed enclosures.
I thought it might be obvious that the shape of vented enclosures will effect performance.
IE. the TL or ML or BLH types. I should have gave a mention to BR's. Thanx Dave.

ah yes, when one a$$ u me s

Even with sealed, I'd still try to avoid cubic or even multiples of dimensions in all but woofers operating over limited bandwidth. Then of course, there's aesthetic considerations - some ratios just look more awkward than others.

really, the nanny edited the first 3 letters of assumes

What a potty mouth!

Your nanny should spank your little bottom!

there are private forums for those kind of discussions, and this is my work computer, so I'll be on my best behaviour
