- FlooringExceptions: Speakers with downward firing ports, woofer drivers (or those with bottom speaker terminals) must maintain the same distance as originally prescribed by the speaker manufacturer, in order to maintain desired acoustic loading of ports or drivers. In this case, if the speaker manufacturer has provided spikes or spacers, these can be placed directly onto the platform, with results superior to placement on ordinary flooring. If rubber or sorbothane feet or pads are on the bottom of the speaker and will directly interface to the platform top, these feet should be replaced or bypassed with solid (that is, having high mechanical transmission characteristics, such as metal) footers of equal thickness, since compliant materials like rubber have poor mechanical transmission characteristics and in addition, exhibit marked storage and release characteristics which seriously damage transient accuracy. B) The connection between the platform and the floor
- CarpetingWhat we're trying to do is give the internally generated vibration of a loudspeaker (which is considerable) an efficient escape pathway into the platform, where it can be converted to and dissipated as heat energy, without reflecting back. In order to do this, best results are realized when the speaker is placed FLAT onto the platform, with NO points, cones, spikes, or other "footers" in between, because this maximizes the area interface between speaker and platform, and thus the energy transfer capacity. The use of cones and spikes is very beneficial on carpeting, because they bypass the carpet, but on a platform designed for energy absorption, the result is a marked reduction in the energy rate that can transfer out of the speaker (akin to mechanical current capacity), and severely reduces the damping power of the platform.
