RE: Decoupling Speakers - Springs vs. Herbie's

Posted by John Elison on September 16, 2020 at 04:47:47:
I think there's something fishy in that graph of vibrations. If you spike a speaker to a concrete slab, it should damp bass frequency vibrations immediately. At least that's what I hear with my speakers. My house is built on a concrete slab and my speakers are spiked to that slab. Bass is tight and controlled. It's only bass frequencies that benefit from spiking speakers to a concrete slab. I don't think it affects midrange or high-frequencies. However, bass becomes noticeably improved in clarity and impact in my system.
If your speakers sounds better when decoupled from a concrete slab floor, I think you probably have defective speakers. I know of no speaker manufacturer who recommends decoupling speakers from a concrete slab. They might recommend decoupling speakers from a suspended wooden floor, but not a concrete slab. At any rate, I've never heard of that.
Good luck,
John Elison
