Floor, dual band, bass-reflex speaker system, volume 20liters, is made of combination of natural wood and MDF. The front wall of the baffle is made of natural wood with a thickness of minimum 50mm and maximum of 80mm. Other walls are made of MDF, covered with a veneer made from natural wood. All edges of the front wall of the baffle are smoothly rounded. The interior of the cabinet consists of nine open chambers made of MDF (CSWA system) with a thickness of 25mm. Three millimeters thick bitumen plates, combined with textile fabric are glued to all free walls of the baffle. This construction efficiently suppresses the stationary wave motion and prevents transfer of vibrations onto the baffle. A new damping material, Twaron® - Angel Hair, is used. It is freely distributed in all chambers. To connect to the amplifier, golden terminals (standard AEC®, PURESONIC®) for bi-wiring, alternatively bi-amping connection are used.

The filtration part contains high-end class passive components from the company Mundorf® or different producers (depending on the requirements of the customer). Design of the crossover, its manufacturing and sound measuring (measuring microphone MIC1 from Holm Acoustic) was made by Adam Vox (Software LspCAD 6 Pro –Ingemar Johansson, IJData, Sweden).

 

The main material used for outside finishing is oak, beech, walnut and natural veneer according to the type of wood used on the front baffle. Selection of material for the surface treatment is also possible according to specific customer requirements.
