We think alike......some random thoughts - I would experiment with some simple dense padding such as used in workshops to keep your feet off the cement floors, its very cheap, comes in large sheets and is only about 1/2 inch thick. If it helps at all you can probably improve on the isolation by adding other dense vibration absorbent stuff in layers. Another Rube Goldberg method might be to put down the absorbent materiel, top it with a sheet of soft wood and then put cones between the speakers and the wood. This would allow speaker's vibrations to disperse some and help isolate the speakers vibrations from the floor.
Coupling vs. Decoupling for Bass Response
My work system is in the hay loft of a converted 100 year old horse barn. The floor is wide pine planks over wood beams and shakes with just the footsteps of someone walking across it. Needless to say it does not help my bass response. I have my LaScalas in this room, which are not exactly known for low bass in the first place. They have a rather large footprint (I believe around 2X3 feet). Any suggestions of some simple (re: inexpensive) ways to get back some of my bass that the floor is eating up? I'm currently using three cones under each speaker, but I'm thinking coupling may be counter-productive. I'm guessing that I should be looking at a means of decoupling. Thanks in advance for any suggestions.
