Hi, all. First-time thread-starter here... I am wondering if anyone has any ideas about ways to dampen floorstanding speaker cabinet resonances to improve micro-dynamics and soundstage imaging. As you can see from the images, I am running a pair of Triangle Zerius 202 speakers in my listening room, and, for the most part, they sound great. I've included some images below. The first two are of my speakers, and the next two are of some marble used to dampen cabinets that I found on the internet (here: http://www.oregondv.com/Loudspeaker_Plinth_Base_Picture Gallery.htm). I'm wondering if these or other ways are available to dampen my speakers' cabinet resonances and achieve better sound. If I went out and bought pieces of marble, how can I calculate weight and size of the marble before buying? And, what would be a good way to couple the marble to the speakers? Any and all ideas are welcome. Thanks!
