Bookshelf speakers on there sides

[biagste]

I have the two front left and right speakers on there sides with the centre in the middle so it all fits on my av rack. Is this not a good idea? after all the centre speakers are really just a normal speaker with two bass drivers on its side????
The speakers in question are Q1010i

Why not try it and see?

Personally i would suggest that it's a myth. Maybe MORE contact with the sitting surface would be preferable?

If the shelves are at the correct height then i can't see the being any difference.

And it wouldn't be hard to blind test - to truly satisfy yourself???
