I bought these stands for my KH 150 speakers and I am very happy with the purchase.
The stands are very well designed and well made. They are super sturdy - there is no wobble at all, and unlike 3rd party stands, the speakers are securely screwed to the stands, so I have zero worry that they will be knocked over by accident.
Also, I really like their design where the supporting rod is at the back of the stand, and the feet of the stands are flat and quite thin, so most of the space under the speakers are still usable.
I would definitely recommend these if your speakers are compatible.
