I had some hemisphere shaped black rubber. Not sure if they wre brand name. They were on my subs for some time. When I heard about the springs, i replaced the rubber ones. Immediately, the bass was detailed, deeper, enveloping. I believe the rubber is for absorptiondamping, springs are isolating. I have a concrete floor. Also, the music used to be much boomier upstairs.
Why spend more than $25 per piece of equipment on vibration reduction?
Do products more expensive than Vibrapods ($24 per set of four) provide superior isolation? I've been pretty happy with the pods, but I wonder whether spending somewhat more, e.g., on Iso-pucks, would bring notably superior results. Or is more a matter of visual, as opposed to audible, aesthetics?
