DIY speaker isolation base for a wood floor

Not on Earth anyway.

exactly, thank you

"everything affects everything else"

you and Geoff head to another planet with different results let us know

you two think you can play something in a room decoupled from that room let us know

you two think you can isolate audio in an active room let us know

oh and good luck, you will have accomplished something no one else in audio ever has

The best isolation I have ever witnesses was Audiogon member folkfreak’s Herzan active isolation platform under his turntable. Very effective, and unfortunately very expensive.

Here's a real talking point: "low mass". My Music Reference RM-10 Mk.2 is a real nice little tube amp, but that niceness is not the result of it's low mass (it weighs only 12 lbs.). My RM-200 Mk.2 also sounds good, and it's a fairly hefty 52 lbs. I won't be selling it and buying a mass-market receiver from the "Golden Age Of High End Audio", the 70/80/90's. More silliness.

Low mass in a loudspeaker driver IS a factor in it's sound quality, for the obvious reason: That mass is moving. The faceplate and chassis of my EAR-Yoshino pre-amp are the heaviest (20 lbs.) of any I've owned, and it's the best sounding as well. I guess in spite of it's mass ;-) .

1. Start with 4 aluminum cones. I used some old Mod Squad Tip Toes.
2. 16x16 slab of granite.
3. 1/8 cork.
4. 1/2 inch neoprene rubber.
5. 1/8 cork.
6. Top with another 16x16 slab of granite.
7. Enclosed with a wood cradle to hide the mechanism.
The granite is from scraps from a shop and was cheap. The added 1/4 inch of neoprene to 1/2 inch thickness did help. Let me hear your thoughts.

Thank you members for your emails!
