I would not advise it. I don't think it would be sufficiently stable. with speakers that tall. I have 11" tall bookshelf speakers on my stands, and these stands work very well with these speakers, but the base of these stands is not really large enough to provide the necessary stability for speakers as tall as yours. And with speakers that tall, I would think it would be too easy to bump them off the stands, and at the height of these stands, there is too much chance of the speakers being damaged if they fell.
