I choose the subdude because of the right fit for my speakers. The idea was a broad flat surface to provide the stability we all want but also the isolation. (Now here comes the coupling decoupling debate). So all in all I now have a large, heavy speaker with a solid foundation creating a much punchier, well defined bass. And let's be real.....I van slide, angle and adjust the position without issue. The 22 x 18 platform also looks great.

I ordered the Subdudes, placed them under my Tekton Pendragons (full range) and thought "oh yaaa". What I had thought was really good became soo, soooo much better. This could go on forever but really, it's only about the basics of good sound. And these basic platforms deliver.
