The Best Speakers the Earth Has to Offer
Sustainability: Why Solid Stone?


Not only does solid stone possess superior resonant and acoustic properties, it is also one of the most sustainable manufacturing materials on earth.
Made from a single solid piece of stone, the rigidity, density, and macromolecular structure of our products' housings provide the ideal substrate for hi-fidelity speakers while also exemplifying the principle of environmental stewardship in loudspeaker design. Our speakers have achieved a level of comparative sustainability not only largely unprecedented in the realm of hi-fidelity audio, but in consumer electronics and entertainment products in general.
Stone is a naturally occurring and practically inexhaustible material. In comparison to the engineered wood products and metals used in most conventional speakers, stone takes virtually no energy to manipulate and has no toxic or environmentally harmful chemicals directly associated with its extraction and fabrication.
The durability and versatility of stone allow us to produce designs that are largely devoid of petroleum products, formaldehyde-treated wood products, synthetics, virgin aluminum, etc. Functional requirements otherwise met by such materials are eliminated through the use of monolithic solid stone components, achieving elegance of design and peerless sustainability of construction.


Life Cycle Analysis


One method of quantifying this sustainability is the use of Life Cycle Analysis (LCA). Broadly defined, LCA is a method for estimating a product's environmental impact at every stage of its existence, from material extraction to disposal and recycling/reuse.


                                        Material cycle


In terms of embodied energy (EE), the quantity of energy a product uses during its life cycle, Audiomasons' speaker production can be as much as fifty times more sustainable than that of conventional alternatives. Our stone housings also do not use, produce, or release any harmful chemicals during their life cycle. This is in contrast to the vast amounts of energy and often harmful chemical agents used to process treated wood, wood products, metals, and synthetic composites used by the majority of industrial manufacturing operations.
To illustrate the sustainability of a single Audiomason speaker, as compared to several conventional speakers fitted with otherwise identical components, we calculated the following:


Material information


The above table is meant to provide perspectice on the comparative energy expended for manufacturing a speaker housing. The manufacture of an Audiomasons speaker over a conventional product manifests a global reduction in energy use equivalent to what the US Department of Energy estimates the average American household uses in as much as a month; this estimate based on comparison to an infinite baffle aluminum housing monitor speakers (for example).


To put that in perspective: that's roughly the same amount of kinetic energy contained in a more than 1500 two-ton trucks going 100mph down a straight road, the combined force of which could likely flatten a small town.
