DIY speaker isolation base for a wood floor
A definite sonic improvement in tightening up the bass.
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.

https://l.facebook.com/l.php?u=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Dwst_XwbwTqk&h=AT2YvQB... Thank you admin for stepping in. This is a link to the Rocky Mountain Audio Fest last year. You can here the difference on your smart phone. I don't have a perfect solution but this video gave me the inspiration to go forward. I do think there is an improvement. If anyone has a platform for me to borrow and return I will. I'm half serious. |
I want a firm solid foundation closer to concrete. We may be over thinking this. A bouncy spring on a bouncy wooden suspended floor? Nothing that gives is going to firm up the bass. Muscle is what is needed to control the woofer. Right? No movement. My platform is not perfect. Would it be better if I place a 36x36 inch slab of granite directly on the floor? |
Two things. Even through the cement slab is very thick and stiff it still moves right along with the movement of the ground due to traffic 🚗 🚙 , subways 🚊 trains 🚞 ocean waves 🌊 on the shore, Earth 🌍 crust motion. The entire house moves. And it moves in 6 directions! 🔛 🔝Springs under components are not “bouncy” as you are imagining them - they actually don’t move visibly when in operation. It’s the combination of mass + springs that provides the mechanical low pass filter. So the object being isolated moves much less with springs under it than without springs. It’s like springs (shock absorbers) on car wheels - they provide a smoother ride, not a rougher ride on solid road surfaces. The more things you isolate with springs the better the bass performance becomes. More dynamic, more slam, lower in frequency and more detailed. |
