Any reason not to place stand mounted speakers upside down?

Just curious about whether others have tried this with any speakers, and what their experiences were.

It would be a shame to waste the Osiris, and they are not easy to ship!

Thanks for the replies! @millercarbon – he did not say that. I misinterpreted one of his responses on the Harbeth forum. He was referring to a speaker in a confined space. Though he did say that it shouldn’t matter (in terms of bass) whether the woofer is on top or bottom.

@teo_audio – I follow you, though it is interesting that Shaw, who certainly is science oriented, insists that Harbeth perform best when the tweeters are at ear height. Presumably he has designed that way.

Brad – thanks for the interesting input.

I am currently using the P3s, but will be using 30.1 or Super HL5+, and the Osiris stands woulds be taller than ideal.

@onhwy61 Of course, but I was asking about the views of using any speakers upside down, not only Harbeth.

Thanks for the anecdote, @returntomusic. As suggested previously, I'd love to use the old Osiris stands if possible, but if it doesn't work out, I can always buy a pair of correct (in terms of height) stands.

Thanks @larryi 

Interesting point.
