This, in my opinion, is the best solution if you want to keep your studio monitors on the table and not on their own floor stand.
Not only it provides height adjustment that is just right for matching twitter to ear height (something you can not get with using foam for decoupling), but it is also of a very good quality.
The product is quite heavy, very robust and sturdy at the same time, it just gives the impression it will last forever.
It also comes with rubber to stick both on top and bottom sides, so your monitor or stand will not move on the table but be very "planted". The rubber at the bottom is more thick for decoupling also. I have an electric table that i can adjust the height and i've been shaking the table to sort of simulate an earthquake, and my feeling is the monitors will never fall off the stand in case of such an event. And of course, they also do a very good job at decoupling them from the table, after all that is why this product was made.
I have another K&M stand for 19" U rack gear and I am very pleased with both of them.
I will buy from the company in the future as well. They really convinced me, both in terms of the quality and also their functionality as well. It looks like the guys at K&M are really thinking about their products and how they design them for functionality without flaws. Highly recommend!!
