I am familiar with Divine Acoustics as a manufacturer of unique and interesting speakers with a wide front resembling an open baffle but a classic cabinet sporting a mid/woofer assisted by a bass-reflex port. Their appearance is absolutely unique. Whilst finish details reveal a tiny manufacturer, it's a very interesting product. I am sure that with appropriate capital to go crazy on CNC machines and enjoy unlimited access to materials, owner/designer Mr. Peter Galkowski could make products look better than most swanky Italian designs. This shouldn't imply that there are present issues. It’s simply that such practical limits force him to think harder than if they weren't. This again is reflected in the details. Generally however it is a high-quality assembly with finely tuned details and a tasty look. An e-mail about a new product showing up in my mailbox in October 2012 was about something completely different however – an anti-vibration platform:

"Hello and welcome! I'm preparing the latest product - Gravity. It will be an anti-vibration platform in the form of a base resting on four legs. It consists of more than 200 elements and uses over 20 different materials including gemstones for vibration damping. Currently I’m assembling the first few units and by the weekend plan on a photo session. Would it be possible to publish photos and a description in this month’s news section? Yours sincerely" - Piotr Galkowski

I assume that this surprise development resulted from working with speakers which due to a very shallow cabinet require an appropriate platform to keep them vertical and at the same time isolated from the floor. In the Electra 2 model for example Mr. Piotr employed a sandwich platform of two outer MDF layers with a central plastic mass. An additional absorber was a layer of cork beneath the speaker. The lot sat on spikes which we also find under the Gravity platform, today's topic.

This platform was designed for CD, DVD and Blu-ray players, amplifiers—especially tube—and turntables. Although it seems to resemble many other such platforms, especially the 3SG30 from Polish maker Rogoz Audio, its design and appearance are quite different. While it’s a platform with a frame supporting an inner shelf, the latter is housed in a type of enclosure and uses a different type of mechanical coupling between support and top. Whilst these are different designs, their similarity results from using round vertical tubes as spiked footers. I assume that their frames are similar too yet here the pipes are not welded together but mounted to the bottom.

That's where the similarities end.
Although it costs surprisingly little, this Gravity device consists of 200 parts. As we already read, it uses 20 materials with different densities and damping factors [these include MDF, HDF, steel, aluminium, various resins, gemstones, PVC, chromium, silica, acrylic, silicone, minerals, cork, oak and beech wood - Ed]. The resonance damping and weight distribution system was created during tests with a variable frequency vibration generator. The designer adds that "this now enables the platform to very effectively suppress vibrations in the range of 40-120Hz which are harmful actions generated by audio transformers and power delivery. The platform rests on four aluminium feet with adjustable chrome spikes. Each foot connects to the platform's lower deck independently by using rigid thick-walled steel tubes coated with black PVC and filled with a mixture of damping materials. Each tube has a different length to suppresses a different range of frequencies."
