Heavy Speakers with Spikes on a Concrete Floor
just found this too after a little more searching https://forum.audiogon.com/discussions/solid-maple-vs-butcher-block I think I need to rethink. I am probably just going to use butcher blocks for a cheap but not cheap alternative for now. |
okay follow up report. I ended up purchasing butcher block acoustic maple blocks, about four inches thick. They are sitting on my carpeted cement floor via spikes. My speaker said atop them with spikes on the back half of the speaker and Hudson sorbothene pods on the front half. And it sounds awesome. A definite improvement and I know this seems crazy. If I used all spikes on the speakers, I lost some bass response, and if I used all sorbothane, it was too much bass. The half and half is the perfect combo. As for the maple blocks, i’m not sure that some of it is just that it raises the speakers up to a better listening height???? But it was an improvement over sitting on the floor. The glued blocks are not supposed to be as good as solid one piece Maple, but for the price of a solid piece of Maple, I was literally able to buy property in Vermont, and soon I will cut down my own Maple tree and produce a real slab for less money |
There is no good reason to use any kind of maple or other block under your speakers on a concrete floor. Some people use them to help isolate the speaker from exciting a suspended floor- e.g. a wood floor. My system has always been set up in a finished basement, dense carpet and padding over concrete slab. All of my speakers are spiked through the carpet to the concrete. FYI a 205 lb speaker with four spikes will present a 51 lb load to each spike - nothing to worry about unless you use the speakers as pile drivers. |
