Absolute fidelity

this system. The spike passes all frequencies to the spike cup, and then depending on the diameter of the spike cup, it passes only frequencies below a particular frequency.

A copper penny gets deformed – the spike making an indentation where it meets the penny, and a little “nipple” on the other side. This still performs the same function as a pin- point suspension system, but at the same time protects your hardwood floor.

Nevertheless, despite the acoustic suspension, if you have a extremely light and resonant floorboards, the acoustic suspension may still transmit sufficient vibrations to make your floor resonate and hence muddy up the bass and the imaging. In that case, it may be necessary to place heavy marble, slate, or granite slabs (at least 100lbs per slab) under the speakers. This slab serves as a foundation on which the acoustic suspension will work.
