Colunas com caixa de betão

São giras.
E para além das qualidades do betão têm altifalantes da Scan-Speak...mas para cozinhar um bom prato não basta dispor dos melhores ingredientes.

As primeiras colunas feitas em cimento foram produzidas pela marca dinamarquesa Avance. O seu fundador Poul Rossing ambicionou em 1973 criar uma caixa que evitasse ao máximo colorações e reverberações.

Todas as colunas eram equipadas com os também dinamarqueses drivers Scan-Speak, tal como estas que referes.

Tenho umas colunas Avance do modelo Magnum, embora a marca em Portugal seja completamente desconhecida e desconfio até que nem haja por cá mais exemplares.


"Poul Rossing's new found philosophy of making luxury speakers affordable for a larger audience immediately became a hit and two years later AVANCE experienced a truly great sales success developing and manufacturing the worlds first asymmetrical AVANCE CONCRETE high end speakers with virtually non-resonant enclosures made of a mixture of cast fibre concrete and glass fibres.

Poul Rossing invested a lot of time and money in measuring and improving the self damping coefficients of concrete by blending concrete with plastic foams etc. At the same time the company became more involved with customising special drive units for the new loudspeakers, whose cabinet-sound coloration showed up to be incredibly low.

Until then most quality wooden loudspeakers had huge amounts of resonant sound coloration – and at the same time were always stereotypically big, rectangularly shaped and either brown or black. Poul Rossing wanted something different to expose the great Danish tradition of design and came up with beautifully pentagonal or pyramidal shaped speakers in white. The sound of the first prototypes was very dynamic and resolution was high, so AVANCE CONCRETE had fine reviews from all over Europe even though the speakers at that time were not sold in big numbers.

Manufacturing cast fibre concrete enclosures in white piano lacquer finish is really time consuming so AVANCE speakers became more expensive. But because the cabinets were incredibly inert and heavy AVANCE CONCRETE loudspeakers provided total lack of conventional cabinet coloration. Particularly in the bass and midrange Poul Rossing’s speakers sounded so much cleaner and reproduced all kinds of music with greater inter-transient silence and more dynamic impact than any other wooden loudspeaker of that time. Therefore AVANCE loudspeakers soon became prestigious and well known in high end society as far away as China, Italy and United States."

E que tal tocam?

Olha, boa ideia. E como tiras belas fotos, tiras-me uma onde fique bem parecido (um milagre).
