Speaker manufacturers are actively experimenting with different materials to create both cabinets and speaker cones.\u00a0It is difficult to name a material that has not yet been tried in one or another structural element of acoustic systems.<\/p>\n

We have collected several interesting models that are examples of an unconventional approach.<\/strong><\/p>\n

Acora Acoustics SRC-2<\/h3>\n

The Canadian company Acora Acoustics, beloved by audiophiles, produces floor-standing speakers in granite cabinets.\u00a0According to the developer, it is this material, coupled with the chosen shape, that makes it possible to do without internal ties and partitions.\u00a0With a fairly modest size, the weight of each column is 110 kilograms!\u00a0The model has a two-way design, in which the mid-range and low-frequency range are sounded by dual 7-inch drivers with cellulose cones, and a speaker with a pure beryllium dome is responsible for the high frequencies.\u00a0The price for a pair of Acora Acoustics SRC-2 speakers is $36,000.<\/p>\n

Technics SB-AFP10<\/h3>\n

Amazing speaker systems from 1988 differ not only in an atypical form factor, but also in the use of unusual materials for the manufacture of speakers at that time.\u00a0Flat dynamic radiators AFP (Acoustic Flat Panels) are equipped with diffusers made of mica and chitin (!), from which beetle shells are made in nature.\u00a0The tweeter has a diamond-coated membrane.\u00a0For that era, these were very expensive speakers – the price was 500,000 yen.<\/p>\n

Mo\u00b0 sound<\/h3>\n

Another original acoustics is made in Austria.\u00a0In the assortment of the company there are several different models, united by one feature – their cases are made of porcelain.\u00a0A special kind of triple-fired porcelain is used, which makes the walls strong enough.\u00a0All the company’s speakers are built on broadband radiators in a closed acoustic design, in total the company produces three bookshelf models Classic, Superior and Augarten, as well as the Bass model, which is a triphonic consisting of two Classic speakers and a subwoofer on a tripod.\u00a0Prices range from 900 euros to 6,600 euros per pair.<\/p>\n","protected":false},"excerpt":{"rendered":"
