"The most important in loudspeakers are the cabinets. No vibrations or coloration should be added to the listening experience. In good samples the cabinet is generally the most costly part of the construction. In Rauna the cabinet-material “concrete” the cheapest, but on the other hand, it is very hard to build a more solid, stable and better acoustical-shaped “box” even if you had unlimited money to spent. That is one reason why Rauna is superior at the pricepoint, delivering a very natural performance, not “caught” in the cabinet.”
