w pokoju odsłuchowym scena zrobiła się szersza i bardziej 3D, mniej ostrych odbić od ścian. Ciekawy modułowy wzór, można składać różne układy. Ciężkie, ale warte ceny.

Stage opened up noticeably after I put these behind the listening spot, less harsh reflections and more depth. The modular tile pattern looks great too.

Hinter dem Horplatz montiert, die Bühne wirkt jetzt breiter und die harten Reflexionen sind weg. Modulares Kachelmuster sieht gut aus. Ist allerdings ziemlich schwer.
