Equarack 8 SM-1 Speaker Mounts 4 per speaker

The very best Footers for speaker I have used. Plenty of Pellets to go around. The Top Disc of the Speaker Mount will accept virtually any stock loudspeaker “spike” in its wide conical counter-bore. Multi-Mount Speaker Mounts provide very secure loudspeaker support! The Speaker Mount is comprised of two parts; an anodized aluminum alloy Base and a stainless-steel Top Disc machined to very close tolerances and beautifully finished. The Speaker Mount has an array of round counter-bores in the top surface of its Base into which the user places from (1) to (16) Viscoelastic Pellets, depending upon the weight to be supported by the Mount. A single Pellet has a maximum weight capacity of 2.5lbs., and each Mount can accept up to (16) Pellets, therefore each Mount has a weight capacity of 40lbs. Higher loading is possible, but will result in declining effectiveness and durability of the Viscoelastic Pellets. The proprietary material, size and shape of the Viscoelastic Pellets are all vital to their extraordinary effectiveness of our loudspeaker isolation mounts. Each Pellet is a tiny "power-plant" of energy conversion. Moreover, unlike the viscoelastic parts in competing products that should be replaced each year - or sooner, the Pellets will provide undiminished performance for at least 5-years and likely much longer if they are not significantly overloaded. The weight distribution of the Loudspeaker to be supported can be determined by the use of a (household) scale, which must be used to calculate the “load” or weight to be supported by each individual Speaker Mount. The Owner’s Manual gives clear, illustrated instructions for weighing and performing these simple calculations. The Speaker Mounts are very easy to assemble using the included Alignment Sleeve; place the required number of Pellets into the Base, slide the Sleeve over the Base, insert the Top Disc into the Sleeve and push down onto the Pellets, then remove the Sleeve. Design & Technology: Multi-Mount Speaker Mounts are unique speaker isolation devices but the technology and application of their isolation and damping features is based upon well-established, irrefutable engineering science that is integral to vibration control in all major industries. Loudspeaker spikes do not isolate - they couple the speakers to the floor! They virtually "nail" the speakers to the floor - making the floor an extension of the loudspeaker cabinet. As such, the loudspeakers are subject to the floor and their performance and sound are altered and colored by the floor. This is one of the main reasons that the same loudspeakers may sound quite different in rooms having different types of flooring and floor construction. Multi-Mount Speaker Mounts provide loudspeakers with user-adjusted, weight-optimized isolation from the floor, and they act as “sinks” that drain and damp loudspeaker cabinet vibration. The Speaker Mounts greatly reduce the transmission of mechanical speaker vibration to the floor and thus to any racks or stands placed upon the floor. This greatly reduces the level of disturbing “noise” that can pass into adjacent rooms or neighbors’ apartments. At the same time, the Mounts isolate the loudspeakers from floor-borne vibratory energy caused by playing music (acoustic energy) and mechanically induced vibration caused by seismic activity, foot-fall, appliances, HVAC, wind, vehicular traffic, etc. Equarack Speaker Mounts are not “tweaks” or “tuning” devices. They are not “additive” devices that shift tonal balance or exaggerate certain frequencies. Instead, they are “subtractive” because they minimize degrading vibratory energy. The resultant positive effects of loudspeaker isolation may vary from subtle to dramatic depending on the types of loudspeakers, building construction, flooring, and listening levels. The Speaker Mounts provide weight-optimzed speaker isolation that will outperform speaker stands, speaker spikes, speaker feet, speaker platforms and speaker bases. Multi-Mount Speaker Mounts, like no other competing devices, provide user-adjustable, optimized isolation in sixteen (16) increments of 2.5lbs. each for ultimate loudspeaker performance. The Speaker Mounts are thereby, precisely weight-matched to the loudspeaker, making them the world's only truly universal loudspeaker isolation mounts! Viscoelastics are weight sensitive. They perform poorly if they are under-loaded, or overloaded. A viscoelastic part provides optimum isolation, only within a narrow weight margin. Most competing devices and systems do not address these crucial limitations at all. Some offer a choice of a few "standard" viscoelastic parts or platforms to cover an excessively wide range of component weights, which is a poor compromise. But even these "better" systems ignore the critical issues of loudspeaker weight distribution and individual isolator loading. Most loudspeakers are significantly heavier (usually in front) where the drivers are located and thereby will exert significantly different loads on the supporting isolators. Multi-Mount Speaker Mounts address this important issue because they are individually optimized (adjusted) for the loads they support. The Viscoelastic Pellets provide superb damping of vibratory energy by hysteresis and superb isolation by both deformation and hysteresis. Unlike most elastomeric “isolators” which behave like an un-damped spring, the Pellets exhibit excellent “shock-rebound” (vertical isolation) properties similar to a high-performance viscous (fluid) shock absorber, in combination with a spring. In addition, unlike “hard” footers and those with thin, laminated or constrained viscoelastics, the Viscoelastic Pellets can deform laterally, and thereby act as elastomeric bearings - providing significant lateral isolation in addition to vertical isolation, for the benefit of the loudspeaker. Loudspeaker Isolation & Damping Explained: A Vibration ISOLATOR is a viscoelastic part or a device that provides relative movement between the supported loudspeaker and the supporting structure or the floor. A Vibration DAMPER is a viscoelastic material or a device that converts vibratory energy into heat - thereby dissipating the vibratory energy. In an automobile, the springs provide isolation and the shocks provide damping but they are not interchangeable! They are interdependant! FOR AUDIO / VIDEO, THE BEST PRODUCTS ARE THOSE THAT PROVIDE ISOLATION AND DAMPING! ISOLATION refers to the process of preventing (minimizing) externally generated vibratory energy from reaching a loudspeaker. Although this includes acoustic or air-borne vibration that is difficult to manage in exposed audio/video equipment, we are primarily concerned with the transfer of mechanical vibration. And, it is essential to understand that there is no significant mechanical isolation provided unless there is relative movement between the loudspeaker and the floor to minimize sympathetic movement with the floor. Therefore, only a device or material that can compress like a spring or deform like an air-bag or a viscoelastic part, or “roll” like a bearing, can be an isolator. Exceptions to these “passive” examples include “active” systems that have electromechanical capabilities. Obviously, hard “spikes”, "cones", and (bare) "platforms" or "shelves" are not vibration isolators regardless of their material composition! However, a platform supported by isolators as part of its design can be an isolation platform. DAMPING is the dissipation of energy in an vibrating structure or loudspeaker. It refers to the process of removing (minimizing) internally generated vibration that is inherent in a loudspeaker AND any external vibration that, for lack of adequate isolation may enter the loudspeaker, by converting the mechanical vibratory energy of solids into heat energy - a process called hysteresis. Vibration damping is generally accomplished by the bonding of viscoelastic materials to the (vibrating) internal surfaces, mechanisms and parts of a loudspeaker and by external coupling to viscoelastic materials or damping devices.
