Has anyone got any additional ideas for general tweaks for my Kef PSW 2010. It currently sits on a slab of 1" thick marble which is coupled to the floor by a set of 3 large Michell Tenderfeet with the aid of some bluetack. http://cgi.trichord.force9.co.uk/acatalog/Michell__Tenderfeet__Cones.html The Sub is connected via a Monsterbass 400 Subcable with Y-splitter. Position and Levels are all set correctly, although maybe a couple of db hot. The sound is overall spot on, but i just wondered if anyone knows how to squeeze every ounce of bass possible. I've heard that sealing the inside joints with silicon may tighten it up further.
